临床电生理检查中,心室早搏刺激后常出现1个或数个非刺激性心室除极波,即心室重复反应(Repetitive ventricular response,RVR)。其临床意义,特别是与恶性室性心律失常的关系仍是争论中的问题。现将有关的研究综述如下。发生机理与分型早期研究者采用窦性心律(NSR)或心房起搏心律(APR)时进行心室单早搏(S_2)或双早搏(S_2S_3)刺激,其诱发的单个或多个非刺激性心室除极波称为RVR。以后有学者采用心室起搏心律(VPR)单早
Clinical electrophysiological examination, ventricular premature beat often appear after stimulation of one or several non-irritating ventricular depolarization, that is, ventricular response (Repetitive ventricular response, RVR). Its clinical significance, especially in relation to malignant ventricular arrhythmias, remains a matter of debate. The related research is summarized as follows. Mechanism and classification of early ventricular premature beats (S_2) or double premature beats (S_2S_3) stimulated by sinus rhythm (NSR) or atrial pacemaker (APR), early induced single or multiple non-irritating ventricles In addition to polar wave called RVR. Later scholars have used ventricular pacing (VPR) single early
