心室晚电位临床意义的探讨

采用信号叠加技术并结合临床探讨了晚电位在正常人和各种心脏病人中的阳性发生率以及与室性心律失常的关系。结果表明，晚电位主要发生于缺血性心脏病，尤其是陈旧性心肌梗塞后伴室速、室颤者（发生率７５％）；正常人，无器质性心脏病的室性心律失常病人，非缺血性心脏病人中的晚电位发生率较低；急性心肌梗塞后的晚电位有动态变化。

Clinical significance on ventricular late potentials

n order to determine the incidence of ventricular late potentiais in normal subjects andthe patients with different kinds.of heart diseases,and its relation to ventriculararrhythmias,275 cases were examined by means of signal-averaged techniques. The re-sults indicated that the late potentials occurred mainly in ischemic heart diseases,especiallyin ventricular tachvcardia and ventricular fibrillation after mvocardial infarction(75%).The incidence of the late potentials was low in the normal subjects,the patients with ven- tricular arrhythmias and no organic heart disease,and the patients with ischemic heart disas-es.The late potentials had dynamic changes after acute myocardial infarction.
