Abstract

We present the case of a patient with incessant slow-fast atrio-ventricular (AV) node reentrant tachycardia induced by dual AV node conduction with aborted conduction to the ventricles. The unapparent conduction over the slow pathway was suspected here because of spontaneous nodal echoes without QRS complexes occurring during sinus rhythm, manifested as isolated premature atrial beats and which repetitively induced the tachycardia.

摘要

我们报告一例患者，其因房室结双径路传导伴心室传导中断，导致持续性慢快型房室结折返性心动过速。此处怀疑存在隐匿性慢径路传导，原因是在窦性心律时出现无QRS波群的自发性结性回波，表现为孤立性房性早搏，并反复诱发心动过速。
