Abstract

Paroxysmal atrioventricular (AV) block is characterized by sudden appearance of complete heart block with no escape rhythm. Three types have been described having different mechanisms namely, vagally mediated, intrinsic, and idiopathic. A rare case scenario is being described with the occurrence of paroxysmal AV block of all three types in the same patient.

摘要

阵发性房室传导阻滞的特征是突然出现完全性心脏传导阻滞且无逸搏心律。已描述了三种具有不同机制的类型，即迷走神经介导型、固有型和特发型。本文描述了一个罕见病例，同一患者出现了所有三种类型的阵发性房室传导阻滞。
