摘　　要：目的将心电图(ECG)预测的心肌梗死相关动脉(IRA)与冠状动脉造影结果进行对比分析,判断错误和无法判断的原因和可能机制。方法收集急性ST段抬高心肌梗死(STEMI)患者,入院12 h行急诊冠状动脉造影。结果选择患者512例,其中424例能够通过ECG判断IRA,52例判断错误,36例无法判断。结论侧支循环等原因影响ECG对IRA的判断。Objective To explore the reason for failed the infarct-related artery（IRA） identification by electrocardiogram（ECG） based on comparison between ECG records and coronary angiographic findings. Methods The 512 consecutive patients with ST elevation myocardial infarction（STEMI） were performed within 12 hours of the symptom onset in all patients. Results Of all 512 patients enrolled, the IRA were correctly identified in 424 cases and identified wrong in 52 cases and could not be identified in 36 cases by ECG. Conclusion Coronary collateral vessel can mislead judgments of the IRA by ECG.
