目的：分析冠心病患者静息心电图特征。方法对1053例患者进行冠状动脉造影，然后根据患者造影结果将其分为单支、两支和三支病变组，分析三组患者入院后心电图资料。结果①一支冠脉血管病变303例，二支冠脉血管病变309例，三支冠脉血管病变441例。②异常Q波351例(33%)、ST段异常747例(71%)、T波异常831例(79%)、完全性左束支传导阻滞168例(16%)及Ⅲ度房室传导阻滞126例(12%)，三组间比较，差异有统计学意义(P<0．05)。结论随着患者冠状动脉血管病变支数增多，异常心电图的检出率明显增高。

Objective To analyze the characteristics of resting ECG in patients with coronary heart disease. Methods 1053 cases of patients were divided into single, two and three lesions according to coronary angiography,we analyzed their ECG da-ta. Results ①303 cases were one coronary vascular disease, 309 cases were two, 441 cases were three .② Abnormal Q wave 351 cases (33%), ST segment abnormalities 747 cases (71%), T wave abnormalitied 831 cases (79%), complete left bundle branch block in 168 cases (16%) andⅢdegree atrioventricular block in 126 cases (12%),the difference was statistically signif-icant among the three groups(P<0. 05). Conclusions With the number of lesions in patients with coronary artery increased, the detection rate of abnormal ECG was significantly increased.
