用计算机进行心电信号叠加记录心室晚电位（ＶＬＰ）是近年来发展的鉴别恶性室性心律失常病人的方法之一，但目前的计算机算法不能检测ＱＲＳ波中的ＶＬＰ，在一定程度上影响了ＶＬＰ的检出率。如果对目前方法所得的叠加心电图进行光滑处理，将经光滑处理和未经光滑处理的叠加心电图相减，则可望显示出寄生于ＱＲＳ波中及ＱＲＳ波终末高频的微小波形，在制定ＶＬＰ的阳性标准后即可判断其中是否存在ＶＬＰ，使ＶＬＰ的检出率得以提高。这种检测方法的正确性还有待于今后的研究验证。
The superposition of ECG signals by computer recording of ventricular late potential (VLP) is one of the methods developed in recent years to identify patients with malignant ventricular arrhythmias. However, the current computer algorithms can not detect VLPs in QRS waves and affect to a certain extent The detection rate of VLP. If the current method of superimposed ECG smoothing, smoothed and unmigrated superposition of ECG subtraction, is expected to appear in the QRS wave and the QRS wave is expected to end the high-frequency micro-wave, in the development of VLP positive criteria to determine whether there VLP, the detection rate of VLP can be increased. The correctness of this test method remains to be verified in future research.
