Lumbosacral osteomyelitis after robot-assisted total laparoscopic hysterectomy and sacral colpopexy. The development of robotic surgery was aided by the Defense Advanced Research Projects Agency, who funded research into the possibility of a remote surgery program for ® battlefield triage. In Europe, it has full regulatory clearance and has the Conformité Européenne mark since 1999 . The benefits for the surgeon include the potential for greater precision, lower error rates, shorter learning curves, and superior ergonomics than conventional laparoscopy. By December 2012, there were 2,585 da Vinci Surgical Systems installed in approximately 2,025 hospitals worldwide with approximately 450,000 robot-assisted procedures performed in 2012, an increase of approximately 25% compared to 2011 . The general definition of technology assessment used was “a comprehensive form of policy research that examines the short- and long-term social consequences of the application or use of technology. This makes them an ideal tool and reference point for systematic reviews of new technology. Equally, the analysis must be transparent and deal with issues of quality-adjusted life-years and cost–benefit analysis as appropriate to the geographical area served. They are a valuable tool for health care policy making and decision making by governments. They concluded that based on the evidence available, the robot-assisted surgery may have a significant impact on many clinical outcomes in patients undergoing hysterectomy. In general, robotic surgery can have an impact on reducing hospitalization costs, but the investment made in acquiring this technology is significant, and institutions that choose to adopt it should make efforts to monitor its costs and outcomes in order to maximize cost-effectiveness within their own center. To decrease costs, centers should maximize caseloads, consider keeping the robot operational for longer durations if possible, and use the technology for multiple indications, particularly those with greater potential 1524 impact on important patient outcomes and savings on institutional costs. One of the key advantages of using robotic technology for gynecological procedures is the reduction in surgeon fatigue and the ability to perform complex surgery with a minimal invasive technique. The system consists of three main components: the console from where the surgeon controls the operation, the patient side cart with four interactive robotic arms to which the ® operating instruments are attached, and the vision system (Figure 103. The EndoWrist instruments used during surgery combines 7 degrees of freedom, with 90 degrees of articulation to provide a range of motion superior to the human hand. It also combines intuitive motion and fingertip control with motion scaling and tremor reduction technology to provide instruments with greater capabilities, and improved surgical dexterity. The principle of robotic surgery is that the surgeon operates unscrubbed while seated at the console, from which they are able to view the operating field in three dimensions through a stereoscopic viewer. It is associated with success rates of 74%–98%, a low recurrence rate, and reduced dyspareunia  when compared with vaginal sacrospinous fixation. Laparoscopic sacrocolpopexy has been shown to have similar outcomes with reoperation rates of approximately 6%–7% and a mesh erosion rate of 3% . Furthermore, the conversion rates reduced with increased operator experience . A study by Akladios assessing learning curves in robotic surgery highlighted that once the learning curve is complete, the 1-year cure 1525 rate was 98%; however, there was a 20% de novo dyspareunia rate .

They do however go far beyond the simple traditional posterior repairs and perineoplasty of old purchase meloxicam in india. The focus of these older procedures is simply to restore and reduce the bulge buy meloxicam cheap, whereas the focus of vaginal rejuvenation is to restore the caliber of the vagina and genital hiatus back to prechildbirth state from the introitus all the way up to the apex order meloxicam 15mg amex. No drop-offs or dips should be felt and there should be no tension placed on the levators that causes lateral banding of the vagina. Additionally, the cosmetic appearance of the introitus and perineal body is also taken into account and requires intricate dissection and repair to not only restore function of the introitus but also obtain an appearance that the woman desires. That look typically is one of the vaginal opening being closed, not gaping or wide open with a normal length perineal body that does not bulge out following the repair. This look is sometimes difficult to obtain, without making the introitus too tight, which will cause pain with intercourse. Posterior Wall, Introitus, and Rejuvenation The posterior vaginal wall is the focus of any vaginal rejuvenation procedure. In a woman with a mild cystocele or mild relaxation of the anterior vaginal wall, a small anterior colporrhaphy can be completed to take care of this prior to repair of the posterior wall. However, one needs to be very careful with this as if the repair of the anterior wall is too aggressive, it will lead to lateral banding and constriction of the vagina, before the posterior wall is even started. An incision is made at the introitus, typically in trapezoid pattern, that will also be used in the perineoplasty portion of the procedure (Figure 116. A small incision is then made in a vertical fashion on the posterior wall, and the vaginal epithelium is dissected off the underlying rectovaginal fascia all the way laterally out to the levators (Figure 116. The dissection must be taken all the way up to the apex of the vagina, as the repair needs to incorporate the entire posterior wall to restore the caliber of the full length of the vagina (Figure 116. The dissection of the vaginal epithelium may be completed with a laser, as championed by Dr. David Matlock, or completed utilizing more standard techniques with sharp scissors or electrocautery. Care of course needs to be taken with any electrical energy source near the rectum. If a rectocele is present, the fascia is repaired in a site-specific fashion with delayed absorbable suture for the first layer of the repair. This may be a lateral repair of the defects, a midline placation, or a combination (Figure 116. The caliber of the vagina is then addressed by plication of the rectovaginal fascia in the midline with delayed absorbable sutures. Levator plication is avoided; however, the diameter of the vagina is constantly measured, and several layers of plication may be needed to reduce the genital hiatus and reduce the caliber of the vagina to an appropriate level (Figure 116. A small amount of vaginal epithelium is then excised and the incision closed in a running fashion. A perineoplasty is then completed, involving a very meticulous and detailed dissection out laterally to obtain the lacerated edges of the deep and superficial transverse perineal muscles and bringing them back together in the midline to achieve uniformity at the same level of the posterior wall repair. The inferior edges of the labia majora that will make up the posterior forchette of the vaginal opening must be marked at the beginning of the procedure so that these edges match up during the closure to form the vaginal opening. An appropriate amount of skin must also be excised from the perineum and introitus to result in a cosmetically pleasing appearance of the opening of the vagina for the patient. A multilayer (typically this may involve four or five layers) is completed at the perineum and introitus (Figure 1737 116. When a repair is primarily for vaginal relaxation for sexual function, it becomes a much more meticulous dissection and repair as the surgeon has to constantly be judging and measuring vaginal caliber to try to restore the entire vaginal length to its prechildbirth state. If this is not done, then the results will be poor and the patients’ sexual function may not change or they will be worse secondary to pain, vaginal shortening, scar tissue formation, and/or constrictions. Postoperative Care Routine postoperative care is given to patients undergoing vaginal surgery. Many of the procedures are undertaken on an outpatient basis, and the surgery is completed under spinal or general anesthesia. A pudendal block may also be completed prior to or during the procedure to help decrease postoperative pain. Vaginal packing is left in for a short period of time and removed prior to the patient being discharged. Routine instructions for vaginal surgery are given to the patient and she is seen in follow-up at 4 weeks postoperatively. The vaginal introitus and caliber are assessed, and if felt necessary, the patient will begin perineal massage in warm water bath for 1–2 weeks prior to resuming sexual relations. Conclusion Vaginal rejuvenation surgery is one of the latest trends in elective vaginal surgery for women. It is a repair of the vaginal caliber in women who suffer from decreased vaginal sensation or of feelings of a loose or wide vagina that affects their sexual life. In many instances, women who present with these symptoms are found to have other pelvic pathologies such as prolapse that must also be addressed during any repair contemplated. Sexual dysfunction or decreased sexual sensation may be the first symptoms that women suffer from in the progression of prolapse, and therefore, a proper exam is vital prior to any repair. We have ample evidence that prolapse and vaginal relaxation can create sexual dysfunction and that repair may reverse these changes in many women. It is important to note that when dealing with sexual dysfunction due to vaginal laxity alone, the surgical repair must be very meticulous and exact in order to enhance sensation and function and not impair it. However, little research exists on the relationship between a woman’s genital image and her sexual function. Realizing one’s genital image is part of one’s body image; it is easy to understand how many women might feel sexually inhibited if they are not comfortable with the appearance of their vagina, vulva, or external genitalia. A survey of 3627 women found that women with positive body images reported more sexual activity, initiation of sexual activity, orgasm, sex with lights on, and greater comfort undressing in front of their partners, trying new sexual behaviors, and pleasing their partner . Cosmetic vaginal surgery is currently steamrolling its way into mainstream culture. There have been many negative comments and editorials written suggesting that both the doctors and the patients should not be pursuing cosmetic vaginal surgery [44–46]. Many of those who imposingly opine are often ignorant of the patient and their disposition as well as their medical conditions and their associated symptoms . Physical symptoms are usually associated with wearing certain types of clothing; engaging in activities such as walking, jogging, exercise, and bicycling; and finally intercourse. Yet, other patients are afflicted with emotional problems such as embarrassment, anxiety, and a loss of self-esteem. Cosmetic vaginal surgery does not always begin and end with labia minora reduction surgery, i. There are many different techniques that can be applied to enhance a woman’s genital cosmetic image. To understand the techniques, a basic understanding of the external genitalia is essential before undertaking surgical procedures.

The term “dual plane” is of the implant are invaluable, particularly considering related to the fact that dissection is partly performed in the patients in which the device becomes palpable and visible. Distortion of the breast while the pectoralis major contracts Dissection is performed not only behind the pectoralis can be very fastidious for the patient, particularly when no major, but also directly over it, detaching the muscle from manipulation or release of the medial and inferior muscular the gland for a variable distance, according to the required insertions has been done.

If under tension the nipple-ridge distance is superior to 8 cm, the patients have a ptosis of the breast that will be corrected with great difﬁ- culty by the implant. Anatomic implants, also called drop devices, have been on the market since many years, with a great variety of shapes and projections; many authors consider them of the greatest importance to obtain in the woman a natural, non-operated look. The main difference between these implants and the round ones resides in the superior pole, which is thinner and can be positioned at different heights with respect to Fig. The implant surface has to capability of receiving the new volume, and thus to their permanently adhere to the patient’s tissues.

The limited medium-term results suggest a higher efficacy than Burch but with more urgency and voiding problems purchase meloxicam 15mg online. After going through a stepwise process of cellular destruction and sterilization buy meloxicam on line, these materials essentially provide a framework of collagen cheap meloxicam 15 mg visa, which lends itself to invasion with fibroblasts and new blood vessels. Whether the tissues become completely replaced by host fibrous tissue or remain intact remains unclear. Of the available xenografts materials, more has been written about porcine dermis. Xenoderm was a dried preparation requiring preliminary soaking before implantation, while Pelvicol is a prewetted dermal graft that handles much like a piece of autologous fascia. Case series presenting early outcomes from Pelvicol implantation  promised encouraging efficacy, but longer-term studies have shown unacceptable failure rates. The material was awkward to handle and was withdrawn from the market by the manufacturers in the mid-1990s. Small intestinal submucosa has also been used for urethral support as well as many other uses. There have been conflicting reports on the extent of tissue reaction related to the use of this tissue [140,141]. Synthetics As aforementioned, the long-term durability of these procedures with graft materials has been questioned, with reports of graft failure and declining success rates over time . As such, the midurethral synthetic sling was developed, replacing the pubovaginal sling as the gold standard for stress incontinence, and thus, polypropylene mesh is worth mentioning here as a graft material though it is discussed at length in another chapter . Nonetheless, patients are not necessarily aware of these differences and should be counseled appropriately prior to any surgical intervention, especially when voicing concerns about mesh placement . As such, patients should be informed that synthetic slings are considered a first-line treatment option for stress incontinence. Attempts to improve this coaptation effect through minimally invasive injection techniques have challenged clinicians for over 50 years. The mechanics of urethral bulking seem to be that by increasing the passive resistance of the urethra, leakage is diminished. The ideal injection material should be nonimmunogenic, thus causing no localized inflammatory reaction; stable chemically; nondegradable so that its bulking effect remains; and easy to inject to minimize the difficulties of surgery. Since most of these agents consist of particles suspended in a carrier gel or fluid, it is also important that the particles are large enough not to be absorbed and risk migration, and for as little carrier gel as possible to be absorbed, which results in reduction in efficacy. The first injection techniques to be tried and reported were by Murless in 1938 . He used sclerosing agent, sodium morrhuate, in 20 women and achieved continence in 17 of them, presumably through the effect of scarring and contracture of the vaginal wall. Quakels in 1955 used paraffin to achieve the same effect, but reports of pulmonary embolism stopped the technique . The speed of this procedure and its apparent efficacy, even if this was lower than conventional surgery, appeared to offer a truly minimally invasive alternative to surgery for women who wanted to avoid the risk of morbidity. However, reports of serious complications began to emerge including periurethral abscess [152,153] pulmonary granulomata [154,155], and obstructive uropathy , and long-term outcomes were observed to deteriorate from 80% initial response to 27% at 3 years  and to 33% at 5 years . Gonzales de Garibay, in 1989, reported an alternative bulking agent that utilized autologous fat cells obtained by microliposuction and reinjected into the periurethral tissues . This had the major advantage of being autologous tissue with no immunogenicity problems, cheapness, and ease of use. However, the initial results were disappointing with only 23% of women improved at 12 months  and none in another study  though Palma achieved 64% cure at 12 months by means of repeated injections . Of the 68 women enrolled, 35 received fat and 33 received saline injections of whom 22% and 20%, respectively, were improved at three months. Much further research and clinical development has continued into the modern era using a variety of injectable materials. In brief, recently developed injectables such as silicon particles and calcium hydroxylapatite can result in an improvement in incontinence, but patients may not necessarily achieve dryness. According to the 2012 Cochrane Review on injection therapy for urinary incontinence, there is insufficient evidence in the use of bulking agents to guide clinical practice, and this is discussed in detail in another chapter . Nevertheless, understanding these procedures is paramount as our current surgical treatment options are based on these fundamental surgical principles. The continued use of what some would regard as archaic may be defensible in experienced hands, where the outcomes are well monitored and known to surgeon and patient alike. Thus, scrutiny of surgical technique and materials is becoming commonplace, ultimately providing better patient care, which is the ultimate goal.

Chapter 4 Atrioventricular Conduction The usefulness of intracardiac recording and stimulation techniques in humans was first realized during its application to patients with disorders of atrioventricular (A-V) conduction. The A-V block has been traditionally classified by criteria combining implications about anatomic site, mechanism, and prognosis. Because intracardiac studies can provide much of this information directly, a classification of A-V block that is applicable to the A-V conduction system as a whole or to any of its components is preferred (Table 4-1). Thus, in our laboratory, we prefer to consider first-degree, second-degree, and third-degree A-V block as prolonged conduction, intermittent conduction, and no conduction, respectively, because it more accurately defines the underlying physiology. For example, in the presence of first-degree block, impulse transmission (output/input) is 1:1 (hence the inappropriateness of the term block), although conduction through the whole A-V conduction system, or any of its parts, is prolonged; in the presence of second-degree block, impulse transmission is less than 1:1; and in the presence of third-degree block, no impulse transmission occurs. Type I second-degree block, to which the eponym Wenckebach block is often applied, is characterized by progressive prolongation in A-V conduction time preceding the nonconducted time in the conducted beat following the blocked impulse. However, careful measurement of intra-His conduction times with stable plunge wire electrodes revealed minimal (1- to 2-msec) increments before the blocked beat, a range that usually falls within the error of measurement of the recording techniques commonly used in humans. Thus, the subdivision of second-degree A-V block into two distinct types may not be sound from a mechanistic viewpoint. Nevertheless, from a practical viewpoint it is worth noting that intermittent conduction (second-degree A-V block) associated with no (or undetectable) preceding increment is a behavior characteristic of the His–Purkinje system. Therefore, block greater than second-degree A-V block includes 2:1 A-V block, high-degree A-V block (≥2 consecutive blocked P waves of intermittent conduction), and complete A-V block with evidence. Theoretically, abnormalities of A-V conduction may result from conduction disturbances in any region of the heart, although certain patterns of block can be localized to specific sites (Table 4-2). In the case of a prolonged P-R interval, intracardiac measurements may show normal intracardiac conduction (e. Hence, precise localization of a conduction disturbance may aid the clinician in planning the therapeutic approach. Because of the lack of complete data, these questions are often answered on subjective rather than objective grounds; nevertheless, the following paragraphs present P. Although there are no anatomic data supporting the presence of specific internodal tracts (anterior, middle, or posterior) that 3 facilitate internodal conduction, preferential pathways of atrial conduction exist, but they appear to be related to the spatial and geometric arrangement of atrial fibers rather than to specialized “tracts. Of interest is the fact that a majority of dogs develop complete A-V block and a junctional rhythm if all three internodal tracts (found in dogs) are sectioned. On the other hand, prolonged A-V conduction (first-degree block) that is due to atrial conduction delay is not uncommon in humans. In all instances, however, delayed activation to the lateral left atrium is present. The assessment of intra-atrial conduction demands the reproducible and accurate timing of local 5 electrocardiograms from specific anatomic sites in the atria. While high-density mapping may be useful to ascertain local atrial defects, fewer points are needed to demonstrate the cause of P-wave abnormalities (in a general way). For the reasons given in Chapter 2, simple measurement of the P-A interval is inadequate for the assessment of intra-atrial conduction. These latter two procedures are not really justified unless a left atrial tachycardia is suspected. For accuracy and consistency, the principles of measurement described in Chapter 2 must be followed strictly. Accuracy is further enhanced by the use of rapid recording speeds (200 mm/sec or greater). A single catheter may be used to map more than one location as long as the rhythm (usually sinus) remains constant, and a reproducible reference electrogram is chosen (e. The mean activation time in a group of 24 patients with normal P waves and the mean values in a group of 15 patients with electrocardiographic left atrial enlargement are shown in Figure 4-2A, B, respectively. Obviously detailed atrial activation mapping using the Carto electroanatomic system is most accurate and is necessary for ablation of left atrial tachyarrhythmias. Normal activation is shown in Figure 4-3 in which activation of the left atrium occurs over Bachmann bundle, with additional conduits through the interatrial septum and coronary sinus (and potentially via interatrial bridges). In this patient, delayed activation of the left atrium (P to coronary sinus) and normal intra- right atrium conduction are shown by the atrial map. Intra-atrial delay involving only the right atrium is far less common, but it is seen in the presence of congenital 6 7 heart disease, particularly the endocardial cushion defects and Ebstein anomaly of the tricuspid valve. The prolonged intra-right atrial conduction time was probably due to longer time necessary to traverse the abnormally large right atrium. The demonstration that intra-atrial conduction delay is responsible for prolonged A-V conduction (first-degree A-V block) may alleviate concern that A-V nodal delay, intra-His delay, or infra-His delay is responsible. The vertical line marks the reference point for measurement and is the earliest evidence of atrial electrical activity. Activation times are plotted from various standard sites in the atria, with mean activation time shown with a bar and number. It occasionally occurs spontaneously as Type I second-degree exit block from an automatic atrial focus in the setting of digitalis toxicity (Fig. A similar phenomenon can be precipitated in the laboratory by rapid atrial pacing, which results in progressive increments in the stimulus-to-A 9 interval until the stimulus is not propagated, at which time the process repeats itself. Such types of intra-atrial delays appear to be substrates for intra-atrial reentry (Chapters 8, 9). Interatrial and intra-atrial dissociation have been observed during atrial tachyarrhythmias, particularly atrial flutter and fibrillation. In such instances, all or some part of the atrium manifests one rhythm while the remainder is activated differently. Atrioventricular Node The A-V node accounts for the major component of time in normal A-V transmission. The range of normal A-H time during sinus rhythm is broad (60 to 125 msec), and it can be profoundly influenced by changes in autonomic tone. Thus, 11 measurements of A-V nodal function over periods of time may not be reproducible. Delay in the A-V node is by far the most common source of prolonged A-V conduction (first-degree A-V block) 12 (Fig. From another viewpoint, most patients (≥95%) with a total P-R interval greater than 300 msec have some degree of A-V nodal delay. It is worth reemphasizing that A-V conduction can vary greatly with changes in the P.
The earlier activation at this site suggests two retrograde atrial breakthrough sites and two bypass tracts purchase meloxicam 7.5 mg online. Fusion is seen in the second and seventh complexes buy cheap meloxicam 7.5 mg line, and total preexcitation over the anterior paraseptal bypass tract is seen in the fourth through sixth complexes order 15 mg meloxicam amex. Note the difference in V-A intervals associated with different H-V intervals with various degrees of fusion. The change in V- A intervals is due to the relative activation of the ventricles over the bypass tract and the time that the normal conducting system activates the ventricles. Patients with multiple bypass tracts have been associated with a higher incidence of ventricular fibrillation according to some investigators, a higher incidence of preexcited tachycardias, and clearly, more complicated anatomy for catheter-based or surgical ablation. Thus, it is imperative that one make every effort to detect their presence during electrophysiologic studies. In the presence of multiple bypass tracts the complexity and number of the potential tachycardia circuits is large (Fig. If one considers the fact that a given patient may have more than two A-V bypass tracts (20% of our patients with multiple bypass have three or more tracts), enhanced A-V nodal conduction, P. In nearly 10% of patients with preexcitation, A-V nodal reentry is present, and in some it is the only arrhythmia (Fig. During the preexcited tachycardia, anterograde conduction occurs over a left lateral bypass tract, and retrograde conduction occurs over a second slowly conducting posterior paraseptal bypass tract. A ventricular stimulus delivered when the His is refractory preexcites the atrium with a shorter V-A interval than during the first three complexes; thus, producing a paradoxical premature capture. This earlier retrograde atrial activation sequence results in subsequent delay of antegrade conduction through the A-V node. This delay allows for retrograde activation over a left lateral bypass tract to be manifested. This left lateral bypass tract was previously concealed by antegrade penetration into it by atrial activation that initiated over the right anterior bypass tract. Schematically shown are six potential mechanisms of arrhythmias with two functioning atrioventricular bypass tracts. Atriald extrastimuli only induced typical A-V nodal tachycardia; orthodromic tachycardia was never observed. Although the authors initially ascribed this syndrome to the presence of an A-V nodal bypass tract, the pathophysiologic basis and clinical significance of the syndrome was clarified in the 1980s through the use of intracardiac recordings and programmed stimulation. A short P-R interval may have many mechanisms including a variant of normal, enhanced sympathetic tone, an anatomically small A-V node, ectopic atrial rhythm with differential input into the A-V node, or isoarrhythmic A-V dissociation. The syndrome, as initially described, requires the presence of paroxysmal arrhythmias in addition to the short P-R interval. Most investigators believe that enhanced A-V nodal conduction (perhaps using 13 14 135 136 137 138 139 140 specialized intranodal fibers) is responsible for the majority of cases , , , , , , , while a minority 3 5 139 140 141 are associated with atrio-His connections. In the latter instance, atrial flutter and fibrillation with rapid ventricular responses are the clinical problem. Controversy still exists concerning the functional significance and the anatomic existence of the posterior intranodal tracts 9 described by James, which are the third possibility. Although there is no anatomic correlate of a specialized intranodal pathway, the complex structure of the A-V node, with areas of tightly packed, longitudinally arranged transitional fibers on the periphery of the node, and a lattice network of more loosely connected fibers around densely packed nodal tissue can provide an anatomic substrate for relatively fast and relatively slow conduction. Electrophysiologic Properties The hallmark of patients with the so-called Lown–Ganong–Levine syndrome is enhanced or accelerated A-V conduction, which more than 90% of the time is due to accelerated conduction through the A-V 135 136 137 138 139 140 141 node. The His bundle in this instance is retrogradely activated from the site of distal His insertion. The short H-V is due to the difference in conduction time from the site of insertion in the distal His bundle to the ventricle and to the conduction time from the site of insertion in the distal His bundle to the proximal His bundle. One must distinguish this “short H-V” from the recording of a distal right bundle branch potential, an anatomically shortened posterior division, or premature insertion of normal-sized bundle branch to the ventricular muscle. Block in the bypass tract can usually be achieved through the use of antiarrhythmic agents or occasionally by the induction of atrial fibrillation. Intra-atrial conduction delays and/or H-V prolongation can produce a normal P-R interval without influencing A-V nodal conduction. In the same vein, the presence of bundle branch block in no way signifies an alteration in A-V nodal conduction. Typical of patients with short P-R intervals (110 msec), A-V nodal conduction time is short (A-H interval, 35 msec), and the H-V interval is normal (H-V = 45 msec). A and B: Atrial pacing does not affect the P-R interval, which remains fixed at 100 msec. C: Proof of that appears during atrial fibrillation in which block in the atrio-His bypass tract occurs and conduction proceeds over the normal pathways. It is imperative to identify the mechanism and characteristics of the type of accelerated A-V conduction since the mechanism of enhanced A-V conduction determines the type of the spontaneous arrhythmias. This can be done by analyzing the response of the A-V conducting system to programmed stimulation and/or drug interventions. If accelerated conduction is due to enhanced A-V nodal conduction, patients should respond to such perturbations qualitatively similar to, but perhaps quantitatively less than, the normal A-V node. In contrast, if accelerated A-V conduction is due to an atrio-His bypass tract, responses characteristic of nodal tissue should not be present. The electrophysiologic characteristics of patients with enhanced A-V conduction are discussed in subsequent paragraphs. The atrial paced cycle length is shown on the abscissa, and the resultant A-H interval is on the ordinate. The response of patients with normal P-R intervals to atrial pacing is shown by the stippled area. Three patterns of response to atrial pacing are observed in patients with short P-R intervals: (1) no A-V nodal delay, characteristic of an atrio-His bypass tract (circles); (2) a dual-pathway response, characteristic of a preferential intranodal pathway (dashed line); and (3) a response qualitatively similar to normal but with a lesser degree of A- H prolongation, compatible with a partial A-V nodal bypass tract, a small A-V node, or an extremely rapid intranodal pathway (solid line). Atrial Pacing 135 136 137 138 139 140 141 142 Several types of responses to atrial pacing have been reported (Fig. This usually takes the form of a smooth, continuous, but blunted prolongation of the A-H interval, or of an initial blunted small increase in A-H interval followed by a significant jump at a critical cycle length, typical of dual A-V 13 14 143 144 nodal pathways. In patients with such blunted responses, the 136 A-H interval is rarely >200 msec, and in the study by Benditt et al. These numbers may vary somewhat, depending on patient selection and adrenergic tone in the laboratory. It is of interest, however, that in both groups the maximum A-H before Wenckebach was similar. In a second type of response, a small increase is followed by a jump in the A-H at a critical paced cycle length with a subsequent gradual increase while maintaining 1:1 conduction at cycle lengths of <300 msec. In such patients, the maximum A-H interval can exceed 200 msec, and the maximum increment in A-H interval will exceed 100 msec because conduction at shortest paced cycle lengths during 1:1 conduction is through the slow A-V nodal pathway.
