心室重复反应(Repetitive Ventricular Response,RVR)是心室电程序刺激过程中常见的一种电生理现象。1973年,Greene等曾指出,RVR的存在强烈提示心室存在着致命性的电不稳定,它与恶性室性心律失常有密切关系;但其后另一些研究却认为RVR对恶性室性心律失常无预测价值。而心室晚电位
Repetitive Ventricular Response (RVR) is a common electrophysiological phenomenon in the process of ventricular electrical stimulation. In 1973, Greene et al. Pointed out that the presence of RVR strongly suggests that there is a fatal electrical instability in the ventricles, which is closely related to malignant ventricular arrhythmias; however, other studies have since concluded that RVR has no effect on malignant ventricular arrhythmias Predicted value. The ventricular late potential
