晚电位是心室存在非同步除极和延缓传导的电活动,出现在 QRS 波终末,伸入到ST 段内的一种高频、低振幅、多形性尖波的电现象,为心电活动周期内折返激动所引起,是室性心律失常的重要因素。本文对110例心电图与晚电位进行了分析.用美国Mortoza 仪器公司生产的 ART 1200 EPX型信息叠加心电图仪和自动描记仪,采用Simson 氏导联连接法,由两人操作校正误差,叠加范围在200—300倍,噪声控制在0.6
Late potential is the presence of non-synchronous ventricular depolarization and delayed conduction of electrical activity in the QRS wave terminal, extending into the ST segment of a high frequency, low amplitude, plethysmographic sharp wave of electrical phenomena, ECG Caused by reentry activities during the cycle, is an important factor in ventricular arrhythmias. In this paper, 110 cases of electrocardiogram and late potentials were analyzed.Adopting the ART 1200 EPX information superimposed electrocardiograph and automatic recording instrument produced by Mortoza Instruments Company of the United States, using the Simson’s lead connection method, the correction error was operated by two persons, 200-300 times, noise control at 0.6
