Abstract

This atypical atrial resetting with ventricular extrastimulus delivered during supraventricular tachycardia is characterized by no capture of local ventricular deflection contralateral to the earliest atrial site and is a finding unmasking the presence of a nodoventricular pathway, the ventricular insertion of which is located apically, away from the mitral annulus.

心动过速时心室外刺激导致的非典型心房复位:机制是什么?
这种在室上性心动过速时通过心室外刺激进行的非典型心房复位的特点是,在最早的心房部位的对侧没有捕捉到局部心室偏转,这一发现揭示了结节性心室通路的存在,其心室插入点位于心尖,远离二尖瓣环。
