摘　　要：目的分析左主干病变冠心病心绞痛患者的心电图改变。方法30例冠脉造影诊断为左主干病变的患者,对其心绞痛发作时各导联ST段的变化及临床资料进行分析。结果30例中除7例急性心肌梗死患者呈现典型心电图演变外,有20例患者ST段广泛压低(5个导联以上)。17例患者胸痛发作的心电图中可见STaVR抬高,其中13例STV1也可见抬高,但是程度均低于aVR导联。结论左主干病变引起心肌缺血的心电图改变表现为广泛导联ST段压低及aVR导联ST段抬高。Objective To analyze ECG changes in patients with angina pectoris and left main stem affected. Methods 30 patients with proved left main stem affection were enrolled in this study. ST segment variation of ECG in all leads collected during angina pectoris attacking were analyzed with clinical data. Results Excepting typical variation of acute myocardial infarction in 7 patients, widespread ST segment depression （more than 5 leads） in 20 patients, ST segment elevation in aVR in 17 patients, and in 13 of these 17, ST segment elevation in V1 also observed, but infra to aVR lead. Conclusion Widespread ST segment depression and ST segment elevation in aVR is well correlated to ischemia caused by left main stem stenosis.
