Abstract

Atrioventricular block (AVB) during atrioventricular nodal reentrant tachycardia (AVNRT) has been well documented, although it is not a common phenomenon. The mechanism for the initiation and resolution of AVB during AVNRT have been postulated. However, the site of AVB and its implication on the reentrant circuit in AVNRT is not clear. We illustrate two examples of AVNRT with AVB and offer further clarification on the site and mechanism of AVB.

摘要

房室结折返性心动过速（AVNRT）期间的房室传导阻滞（AVB）已有充分记录，尽管这并非常见现象。关于AVNRT期间AVB的起始和消退机制已有推测。然而，AVNRT中AVB的部位及其对折返环路的影响尚不清楚。我们展示了两例伴有AVB的AVNRT病例，并对AVB的部位和机制做进一步阐释。
