摘　　要：缺血性心肌病（ICM）是冠心病的一种特殊类型或晚期阶段,ICM心律失常以室性期前收缩最多见。12导联动态心电图中的形态可对室性期前收缩起源部位进行定位,本研究旨在分析ICM及非器质性心脏病室性期前收缩起源部位差异。Three hundred patients were divided into ischemic cardiomyopathy（ICM）group（n=150）and inorganic cardiopathy group（n=150）according to the coronary angiography,echocardiogram and dynamic electrocardiography.The incidence of multifocal ventricular premature beats（VPBs）was 85.3% in ICM group,and monophyletic VPBs was 89.3%in inorganic cardiopathy.The incidence of VPBs from the left ventricular,the left ventricular anterior wall and left ventri-cular apex were 55%,21.2% and 14.7% respectively in ICM group,while in inorganic cardiopathy group these indexes were 26.7%,6.8% and 4.4% respectively,showing significant differences（all P〈0.05）.
