Abstract

We present a case of orthodromic atrioventricular re-entrant tachycardia exhibiting both right and left bundle branch block pattern wide QRS morphologies caused by bilateral bystander nodoventricular (NV) accessory pathways. These wide QRS morphologies came from pre-excitation accompanied by delta waves. In the context of NV accessory pathways, left-sided manifest NV accessory pathways are rare.

摘要

我们介绍了一例直行房室折返性心动过速，表现出左右束分支传导阻滞型宽QRS形态，由双侧旁观者脑室（NV）辅助途径引起。这些广泛的QRS形态来自伴随δ波的预激发。在NV附属途径的背景下，左侧明显的NV附属途径很少见。
