心室晚电位（Ｖｅｎｔｒｉｃｕｌａｒｌａｔｅｐｏｔｅｎｔｉａｌ，ＶＬＰ）阳性，常常是致命性心律失常（室性心动过速和／或心室纤颤）的先兆，与猝死密切相关。Ｓｉｍｏｎ等观察室速被抗心律失常药物控制，但心室晚电位的间期和形态没有变化，Ｇａｒｄｅｎ等认为抗心律失常 Ventricular late potential (VLP) is positive, often a precursor to fatal arrhythmias (ventricular tachycardia and/or ventricular fibrillation), and is closely related to sudden death. Simon et al observed that the ventricular tachycardia was controlled by antiarrhythmic drugs, but there was no change in the interval and shape of the ventricular late potential. Garden et al thought antiarrhythmic
