摘要

我们报告一例长RP’型心动过速，诊断为快-慢房室结折返性心动过速（AVNRT）伴旁观者结室通路（NVP）。基底部和心尖部对右心室外刺激的不同反应突出了NVP附着在解剖上的接近性，有助于诊断。

Differential response to right ventricular extrastimuli from the base and apex during long RP′ supraventricular tachycardia

We report a case of long RP′ tachycardia diagnosed as fast–slow atrioventricular nodal reentrant tachycardia (AVNRT) with a bystander nodoventricular pathway (NVP). Differential responses to right ventricular extrastimuli from the base and apex highlighted the anatomical proximity of the NVP attachment, contributing to the diagnosis.
