Rate‐Related and Autonomic Effects on Atrioventricular Conduction Assessed Through Beat‐to‐Beat PR Interval and Cycle Length Variability

Atrioventricular Conduction Variability. Introduction: Atrioventricular AV) conduction time varies on a beat‐by‐beat basis in response to the influences of cardiac efferent autonomic activity and rate‐dependent electrical recovery processes. The goals of this study were to distinguish these effects on AV conduction time and to compare the variability in sinoatrial and AV nodal function.
