The second one crucial visible advisor to Cardiac Electrophysiology

Following the bestselling Cardiac Electrophysiology: a visible consultant for Nurses, Techs, and Fellows, this publication builds upon the fundamental options of electrophysiology brought within the first quantity and courses the reader to a closer realizing of cardiac electrophysiology via operating via ordinarily encountered situations within the EP lab. forty five full-page panorama, top quality colour intracardiac tracings are offered as every-day observations and unknowns, by way of annotated tracings and discussions that emphasize a scientific method of the translation of EP tracings.

Authored through a group of specialists, Cardiac Electrophysiology: a complicated visible advisor for Nurses, Techs, and Fellows is a useful source, supplying very good assistance in constructing the data and talents required to perform medical cardiac electrophysiology.

Sample text

As mentioned previously, this is a form of functional block and is a normal physiological phenomenon. In this example, a R B B B spontaneously resolves. Note the intermediate Q R S morphology just before complete normalization. I n Figure 1, t he i n itia l R B B B occu r s qu ite prox i ma l ly i n t he bundle. The wave of depolarization continues to conduct down the left bundle, through the interventricular septum and retrograde up the right bundle. The collision point between the antegrade and retrograde waves is quite proximal in the right bundle.

The S 2 blocks and the 2 subsequent beats are junctional. Figure 2 : In this figure, an S 3 is added after the same S1 S 2 we see in Figure 1. In this sequence, the pause following the S 2 is interrupted by the S 3 , which appears to conduct. There are also 2 possible explanations for this response: 1. The S 2 is conducted down a slow pathway and the S 3 blocks. If this were the case, the S 3 would not be able to penetrate the AVNRT circuit since the antegrade fast pathway would be refractory and the slow pathway is being used.

T h i s mea n s t hat t he wave of depola r i zat ion generated by the ju nctiona l beat retrogradely penetrated the AV node ( just as an extra-stimulus would), causing the AV node to decrement when the next sinus beat arrives. In other words, the junctional and sinus beats in sequence, produced the same response as a tightly coupled “ S1 S 2 ” from either the atrium or the ventricle. Another possible explanation is that the junctional beat could have concealed into the AV nodal fast pathway, rendering it refractory, thus forcing the sinus beat to conduct over a slow pathway.
