Abstract

This case report describes a patient with chronic chagasic myocarditis who presented with a unique tachycardia-dependent or phase 3 aberrant ventricular conduction. The electrocardiogram showed sinus tachycardia with sequences of alternate and progressive right bundle branch block, that is, Wenckebach periods of alternate beats. We postulated the existence of functional longitudinal dissociation in atrioventricular conduction axis, responsible for the alternant normal and Wenckebach beats.

摘要

本病例报告描述了一名患有慢性恰加斯性心肌炎的患者，其表现为一种独特的心动过速依赖性或3相室性传导异常。心电图显示窦性心动过速，并伴有交替性和进行性右束支传导阻滞序列，即交替搏动的文氏周期。我们推测房室传导轴存在功能性纵向分离，这是交替出现正常搏动和文氏搏动的原因。
