房室交接区是正常窦性激动下传心室的必经之路，也是心律失常最常涉及的部位，因此房室传导功能的临床电生理学有特殊的重要性。房室传导功能大致可区分为传导功能正常，过速或称加速和阻滞三类，本文重点讨论房室阻滞的电生理学。正常房室传导功能的电生理学指标：1．体表心电
Atrioventricular transfer area is normal sinus motility pass ventricular route, but also the most commonly involved parts of arrhythmia, atrioventricular conduction function of clinical electrophysiology has special importance. Atrioventricular conduction can be roughly divided into normal conduction, over-speed or acceleration and retardation of the three categories, this article focuses on the electrophysiology of atrioventricular block. Electrophysiological indicators of normal atrioventricular conduction function: 1. Surface ECG
