摘　　要：目的结合冠脉造影分析心电图V1导联在判断前降支病变位置中的价值及临床应用。方法入选106例因急性前壁心肌梗死行冠脉造影检查的患者,并对其发病后心电图V1导联ST段抬高的程度进行分析。结果冠脉造影发现,前降支近段病变者,V1导联ST段明显抬高≥2.5mV;前降支远段病变者,V1导联ST段抬高<2.5mV。同时近段病变者行急诊PCI术的成功率高于远段病变者。结论急性前壁心肌梗死患者,心电图V1导联ST段的变化可以预测前降支闭塞的位置,对治疗有一定的指导意义。Objective To explore the value of lead V1in evaluating the occlusion site of left anterior descending branch in patients with coronary artery disease （CAD）. Methods ST segment elevation in lead V1 were analyzed in 106 patients who had been diagnosed acute anterior myocardial infarction by coronary arteriography. Results ST segment elevation in Lead V1≥2.5mV in patients whose coronary artery occlusion located in proximal end of the left anterior descending branch（A）. In contrast,ST elevation in lead V1〈2.5mV in patients whose coronary artery occlusion located in distal end of left anterior descending branch （B）. In patients whose coronary artery occlusion in proximal end of left anterior descending branch,achievement ratio of emergency PCI is more than patients whose coronary artery occlusion located in distal end of left anterior descending branch. Conclusions ST segment elevation in lead V1 can forecast the location of left anterior descending occlusion,and be helpful to the treatment.
