Ventriculoatrial Conduction Time During Bundle Branch Reentrant Beat Initiating Orthodromic Tachycardia: A Simple and Reliable Method for Localization of Accessory Pathways
Abstract:VA Interval Via Accessory Pathway During Bundle Branch Reentry. Bundle branch reentrant (BBR) complex is commonly induced during programmed ventricular stimulation with single ex‐trastimulus. In patients with atrioventricular accessory pathway, BBR beat frequently triggers orthodromic tachycardia. This study was designed to determine whether evaluation of the ventriculoatrial conduction time during BBR (VABBR) induced with right ventricular extrastimulation (i.e., left bundle branch block morphology) can separ… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
