室性时相性房内差异传导(Ventriculopha-sic aberrant atrial conduction)系指与心室激动时相有关的一种房内差异传导。作者曾报道过一例Ⅲ°房室传导阻滞伴室性时相性窦性心律不齐和P波改变,并用阿托品消除室性时相性窦性心律不齐后,凡发生在QRS波群后0.20秒的Q-T间期内的P波仍示明显形态改变。当时由于这种现象国内、外尚未见报道,暂称为“室性时相性房内差异传导”。近来又发现一例心房扑动患者,凡发 Ventriculopha-sic aberrant atrial conduction refers to an intra-atrial differential conduction associated with the ventricular activation phase. The authors have reported a case of Ⅲ ° atrioventricular block with ventricular sinus rhythm and P wave changes, and the elimination of atrial septal sinus atrial arrhythmia, where occurred in QRS complex after 0.20 seconds P wave QT interval still showed significant changes in morphology. At that time, because of this phenomenon at home and abroad have not been reported, tentatively referred to as “ventricular differential sex ventricular conduction.” Recently found a patient with atrial flutter, where hair
