房室结多径传导较为少见,其发生折返性室上速的电生理特征国内报道较少。我们经心内电生理证实的4例房室绪多径传导中,有3例诱发出折返性室上遗,现将其电生理特征分析如下: 材料和方法四例患者中3例有心动过速发作史,1例因窦性心动过缓行心脏电生理检查。在未用 Atrioventricular nodal multipath conduction is relatively rare, the occurrence of reentry ventricular tachycardia electrophysiological characteristics of the domestic less reported. We confirmed by electrophysiological electrophysiological 4 cases of atrioventricular multi-path transmissibility, 3 cases induced reentry ventricular sequestration, and now its electrophysiological characteristics are as follows: Materials and methods 4 cases of patients with heart tachycardia 3 A history of rapid onset, 1 case of cardiac electrophysiological examination due to sinus bradycardia.
