Abstract

We present a case of persistent dual AV node conduction during AV node reentry tachycardia as a new clinical manifestation of 2-for-1 AV node conduction. The interpretation of the complex physiology ponders the possibility of an accessory pathway mediated atrioventricular reentry existing with more ventricular than atrial events.

摘要

我们报告一例房室结折返性心动过速期间持续性双房室结传导的病例，这是1:2房室结传导的一种新临床表现。对这种复杂生理现象的解读引发了一种可能性，即存在一条旁路介导的房室折返，心室事件多于心房事件。
