Criteria, old and new for differentiating between ectopic ventricular beats and aberrant ventricular conduction in the presence of atrial fibrillation. Mechanisms of Supraventricular Tachycardia Our concepts of arrhythmogenic mechanisms have evolved over the past century. Tachycardias that are due to enhanced automaticity, either normal or abnormal, can in general be neither predictively initiated nor terminated by electrical stimulation. Although experimental models suggest that annihilation of an automatic focus (not a tachycardia) is possible,3 this is not predictable. The most common response of automatic rhythms to overdrive pacing is either overdrive suppression or no effect whatsoever. Specific responses such as (a) a direct relationship between the coupling interval or paced cycle length initiating the rhythm and the interval to the onset of the rhythm and early cycle length of the rhythm and (b) overdrive acceleration are typical of such arrhythmias and distinguish them from reentrant arrhythmias (see following discussion). The following three conditions are required for the initiation and maintenance of a reentrant rhythm: (a) at least two functionally (or anatomically) distinct potential pathways that join proximally and distally to form a closed circuit of conduction; (b) unidirectional block in one of these potential pathways; and (c) slow conduction down the unblocked pathway, allowing the previously blocked pathway time to recover excitability; that is, the conduction time along the alternative pathway must exceed the refractory period of the initially blocked pathway. If, and only if, conduction delay and refractoriness in both pathways are appropriate, a continuously circulating wavefront of electrical activity will ensue, resulting in a tachycardia. The sine qua non of a reentrant arrhythmia is the ability to reproducibly initiate the tachycardia by timed extrastimuli (particularly in association with evidence of conduction delay and block). Similarly, programmed stimulation can also reproducibly terminate the tachycardia. The mode of initiation and response to stimulation during a reentrant tachycardia differs from that of triggered activity. Timed extrastimuli are more effective than rapid pacing for initiation; there is no direct relationship of pacing cycle length or coupling of extrastimuli to the interval to the onset of the tachycardia or cycle length of the tachycardia; and resetting or entrainment of the tachycardia in the presence of fusion can be demonstr-ated. After a tachycardia has been initiated, the stimulator is synchronized in, and triggered by, a suitable intracardiac P. One or more extrastimuli and overdrive pacing are then introduced to modify (reset, entrain, or terminate) the arrhythmia. The mode of initiation of the tachycardia, with particular attention to the site of conduction delay, which appears requisite for the development of the arrhythmia: to help distinguish reentry from triggered activity,4,7 one should also analyze the relationship of the basic drive cycle length and the coupling interval of the extrastimulus that initiates the tachycardia to the onset of the tachycardia and the initial cycle length of the tachycardia. The effect of bundle branch block, spontaneous or induced, on the cycle length and ventriculoatrial (V-A) conduction time during the tachycardia. The requirement of atrial, His bundle, and/or ventricular participation in the initiation and maintenance of the tachycardia, that is, the effect of A-V dissociation or variable A-V or V-A conduction on the tachycardia. Response to such stimulation allows one to assess the role of atrial, His bundle, and ventricular participation in the tachycardia and can be used to distinguish atrial tachycardia, A-V nodal tachycardia, and tachycardias using concealed accessory pathways from one another. Responses to extrastimuli can establish and quantitate the presence of an excitable gap within the reentrant circuit. This allows one to characterize the properties of the tachycardia circuit as well as to establish which components of the heart are required to maintain the tachycardia. If conduction down the alpha pathway is slow enough to allow the previous refractory beta pathway time to recover, an atrial echo results. If, however, the alpha pathway does not itself recover excitability in time to permit subsequent antegrade conduction, only a single atrial echo results. Because of the longer antegrade conduction time, the alpha pathway has now had more time to recover excitability, and a sustained tachycardia results. The beta pathway has fast conduction and long refractoriness, and the alpha pathway is slowly conducting with relatively shorter refractoriness. If conduction down the alpha pathway is not slow enough to allow the previous refractory beta pathway time to recover reentry will occur. Because of the longer antegrade conduction time, the beta pathway has now had more time to recover excitability, and a sustained tachycardia results. Jalife29 has elegantly shown that the jump in conduction times and isolated reentry can occur in a nonhomogenous linear structure if conduction occurs electrotonically across an area of block. Using a sucrose gap model, he demonstrated classic dual-pathway responses in isolated Purkinje fibers. Antzelevitch and Moe30 demonstrated similar responses in an ischemic gap preparation. Thus, electrotonic propagation clearly can produce dual-pathway responses in the absence of longitudinal dissociation and even can produce reflection of the impulse, a form of microreentry, at least for isolated beats. Nodal fibers are not inexcitable, and they conduct by slow responses31,32 and not solely by electrotonic interaction. A: In sinus rhythm, the impulse conducts over the fast pathway, giving rise to a normal P-R interval, as in Figure 8-1. The impulse conducting over the fast pathway tries to return up the alpha pathway, but it has not recovered excitability, so no echo occurs. In canines the posterior extension and transitional tissue in the posterior triangle of Koch are longitudinally arranged parallel to the tricuspid annulus with scant side-to-side connections. The anatomic characteristics create nonuniform anisotropic properties that could lead to saltatory conduction analogous to that shown by Spach et al. Recently Spach and Josephson37 showed that marked nonuniform anisotropic conduction is present in the posterior triangle of Koch in canines. All models in which discontinuous propagation occurs can give rise to input–output responses analogous to dual pathways. In nonuniform anisotropic tissue, responses to premature stimuli can create functional longitudinal dissociation and sustained reentry. Data in humans supporting the dual-pathway concept include the findings of two P-R or A-H intervals during sinus rhythm or at similar paced cycle lengths (Fig. In the top and bottom panels, the atria are being paced at a cycle length of 700 msec. In the top, the A-H interval is 135 msec and is fixed and in the bottom, a totally different, markedly longer A-H interval (230 msec) is present. Two A-H intervals at the same paced cycle lengths suggest dual A-V nodal pathways. While much of the literature implies that the fast and slow pathways are anatomically distinct structures, there is no anatomic evidence to support this concept.

Use the t distribution to find the reliability factor for a confidence interval based on the following confidence coefficients and sample sizes: a Confidence coefficient glycomet 500mg low cost metabolic disease and obesity. In a study of the effects of early Alzheimer’s disease on nondeclarative memory cheap glycomet 500 mg with mastercard blood glucose 77, Reber et al cheap 500 mg glycomet overnight delivery diabetes symptoms 19 year old. The eight subjects in the sample had Category Fluency Test scores of 11 order 500 mg glycomet mastercard type 2 diabetes test kit, 10, 6, 3, 11, 10, 9, 11. Assume that the eight subjects constitute a simple random sample from a normally distributed population of similar subjects with early Alzheimer’s disease. For each group, determine the following: (a) What was the sample standard deviation? One of the variables of interest was the laxity of the anteroposterior, where higher values indicate more knee instability. The researchers wanted to assess competence in performing clinical breast examinations. The following data give the number of breast examinations performed for this sample of 10 interns. From each of the populations an independent random sample is drawn and, from the data of each, the sample means x1 and x2, respectively, are computed. We learned in the previous chapter that the estimator x1 À x2 yields an unbiased estimate of mÀÁ1 À m2, theÀÁdifference between the population means. We also know from Chapter 5 that, depending on the 1 1 2 2 conditions, the sampling distribution of x1 À x2 may be, at least, approximately normally distributed, so that in many cases we make use of the theory relevant to normal distributions to compute a confidence interval for m1 À m2. When the population variances are known, the 100 1 À a percent confidence interval for m1 À m2 is given by sﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ s2 s2 ð x À x z 1 þ 2 (6. When the constructed interval does not include zero, we say that the interval provides evidence that the two population means are not equal. In a large hospital for the treatment of the mentally challenged, a sample of 12 individuals with Down’s syndrome yielded a mean of x1 ¼ 4:5mg=100 ml. In a general hospital a sample of 15 normal individuals of the same age and sex were found to have a mean value of x2 ¼ 3:4. If it is reasonable to assume that the two populations of values are normally distributed with variances equal to 1 and 1. Since the interval does not include zero, we conclude that the two population means are not equal. If the population variances are unknown, we use the sample variances to estimate them. The mean number of cigarettes smoked daily at the close of the program by the 328 women who completed the program was 4. Among 64 women who did not complete the program, the mean number of cigarettes smoked per day at the close of the program was 13 with a standard deviation of 8. We wish to construct a 99 percent confidence interval for the difference between the means of the populations from which the samples may be presumed to have been selected. Solution: No information is given regarding the shape of the distribution of cigarettes smoked per day. Since our sample sizes are large, however, the central limit theorem assures us that the sampling distribution of the difference between sample means will be approximately normally distributed even if the distribution of the variable in the populations is not normally distributed. We may use this fact as justification for using the z statistic as the reliability factor in the construction of our confidence interval. Also, since the popula- tion standard deviations are not given, we will use the sample standard deviations to estimate them. The point estimate for the difference between population means is the difference between sample means, 4:3 À 13:0 ¼ À8:7. The estimated standard error is sﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ 2 2 5:22 8:97 sx1Àx2 ¼ þ ¼ 1:1577 328 64 6. We must know, or be willing to assume, that the two sampled populations are normally distributed. With regard to the population variances, we distinguish between two situations: (1) the situation in which the population variances are equal, and (2) the situation in which they are not equal. Population Variances Equal If the assumption of equal population variances is justified, the two sample variances that we compute from our two independent samples may be considered as estimates of the same quantity, the common variance. It seems logical, then, that we should somehow capitalize on this in our analysis. This pooled estimate is obtained by computing the weighted average of the two sample variances. If the sample sizes are equal, this weighted average is the arithmetic mean of the two sample variances. If the two sample sizes are unequal, the weighted average takes advantage of the additional information provided by the larger sample. The pooled estimate is given by the formula ð n À 1 s2 þ n À 1 s2 2 1 1 2 2 sp ¼ (6. Methods that may be used in reaching a decision about the equality of population variances are discussed in Sections 6. The authors were addressing the problem of substance abuse issues among people with severe mental disorders. One of the outcome variables examined was the number of inpatient treatment days for psychiatric disorder during the year following the end of the program. For 10 subjects with bipolar disorder, the mean number of psychiatric disorder treatment days was 8. We wish to construct a 95 percent confidence interval for the difference between the means of the populations represented by these two samples. We can say this because we know that if we were to repeat the study many, many times, and compute confidence intervals in the same way, about 95 percent of the intervals would include the difference between the population means. Since the interval includes zero, we conclude that the population means may be equal. As a practical rule in applied problems, one may wish to assume the inequality of variances if the ratio of the larger to the smaller variance exceeds 2; however, a more formal test is described in Section 6. The problem revolves around the fact that the quantity ð x1 À x2 m1 À m2 sﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ s2 s2 p p þ n1 n2 does not follow a t distribution with n1 þ n2 À 2 degrees of freedom when the population variances are not equal. Consequently, the t distribution cannot be used in the usual way to obtain the reliability factor for the confidence interval for the difference between the means of two populations that have unequal variances. The solution proposed by Cochran consists of computing the reliability factor, t 0 , by the following formula: 1Àa=2 0 w1t1 þ w2t2 t1Àa=2 ¼ (6. An approximate 100 1 À a percent confidence interval for m1 À m2 is given by sﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ s2 s2 0 1 2 ð x1 À x2 t 1Àa=2 þ (6. Recall that among the 18 subjects with schizophrenia, the mean number of treatment days was 4. In the bipolar disorder treatment group of 10 subjects, the mean number of psychiatric disorder treatment days was 8. We assume that the two populations of number of psychiatric disorder days are approximately normally distributed. We wish to construct a 95 percent confidence interval for the difference between the means of the two populations represented by the samples. Reference to Appendix Table E shows that with 17 degrees of freedom and 1 À :05=2 ¼ :975; t1 ¼ 2:1098.

A hypothesis for the natural history is presented with possible implications for preventative strategies. During pregnancy the endopelvic fascial attachments of the bladder neck and distal sphincter are weakened possibly due to hormonal influences [2]. Progesterone reduces urethral closure pressures and produces connective changes [3,4] that probably contribute to the high incidence of any antenatal incontinence. If the endopelvic fascial attachments and sphincter function are not damaged at delivery, then the changes seen antenatally are likely to revert to the nonpregnant state with the return of urethral function and continence. However, if these structures are damaged or are inherently weak in the nonpregnant state, then recovery might not arise. Support for this hypothesis comes from studies suggesting the presence of a constitutional factor, e. This, along with further deliveries, aging, menopause, and muscle weakness, seems to increase the risk of long-term incontinence [10]. In a study of women reassessed 6 years after childbirth [13], there was a rate of new-onset incontinence of approximately 30% in women who had been continent at 3 months postpartum. However, in 27% who were incontinent at 3 months, there was spontaneous remission at 6 years. Of particular interest were those women who were incontinent prior to pregnancy; there was a markedly increased risk for leakage at 6 years. These interesting findings suggest that there are women at risk of incontinence, while in others there is spontaneous remission. Based on data from a systematic review, during the first 3 months postpartum, the pooled prevalence of any postpartum incontinence is 33%, with longitudinal studies showing small changes in prevalence in the first year after childbirth [5]. A larger 2-year study of 64,650 women aged 36–55 years showed complete remission in 13. A 2-year study of noninstitutionalized women over 60 years showed a 1- year remission rate of 12% [24]. A study followed 2025 women aged over 65 years for 6 years (baseline prevalence of urgency incontinence was 36. This study showed for urgency incontinence, the 3-year incidence and remission rates between the third and sixth years were 28. For stress incontinence, the 3-year incidence and remission rates between years 3 and 6 were 28. A longitudinal Swedish population-based study of over 100 women from 1991 to 2007 showed incidence and remission rates of 21% and 34%, respectively [14]. The reported incidence for cystocele is around 9 per 100 woman-years, 6 per 100 woman-years for rectocele, and 1. A 4-year observational study [27] in postmenopausal women showed an overall 1- and 3-year prolapse incidence of 26% and 40%, respectively. This study [27] also showed a 1- and 3-year resolution risk of 21% and 19%, respectively. The study also showed that over 3 years, the maximum vaginal descent increased by at least 2 cm in 11% of the women and decreased by at least 2 cm in 2. In older age groups (>70 years), many are symptomatic and approximately 11% will undergo surgery, but there are few data on the numbers treated conservatively, e. The majority (78%) demonstrated no change in the leading edge of the prolapse between the first and the last visit, following which 63% still continued observation [32]. Prevention can be classified as primary (interventions in asymptomatic individuals to reduce known risk factors for the development of a disease) or secondary (to detect symptoms at an early stage and to intervene to stop further development or to improve the prognosis of the condition). To stop recurrence of an illness or preventing it becoming chronic is tertiary prevention. There are known predisposing factors such as age, obesity, family history, parity/vaginal childbirth, and surgery. Identification of individuals at risk might help with implementing preventative measures. Although the prevalence of incontinence is increased in the elderly, the two do not necessarily have a cause-and-effect relationship; other pathological processes associated with aging might be responsible. Likewise, management of other risk factors such as chronic cough, smoking, and adjusting medication that has an adverse effect on the bladder could help incontinence (e.
