从临床心电生理检查看体表叠加平均心电图体表叠加平均心电图（ＳＡＥ）是把计数化的心电波形用计算机叠加平均以从体表检出用通常心电图不能识别的微伏特单位微小电变化的方法，本法最初应用于检查Ｈｉｓ束电位。最近主要用于检查心室晚电位（ＬＰ）。本文从电生理学观点... From the clinical electrophysiological examination to see the superposition of the average body surface ECG average superimposed mean electrocardiogram (SAE) is the count of the ECG waveform superimposed by the average of the computer to detect the surface of the body with a small ECG can not be identified micro-volts small changes Method, the law was originally applied to check the His beam potential. Recently mainly used to check the ventricular late potential (LP). This article from electrophysiology point of view ...
