急性心肌梗死心电图对梗塞相关动脉的预测价值

Predictive Value of Surface Electrocardiogram for Infarct-related Artery in Patients with Acute Myocardial Infarction

目的:探讨急性心肌梗死患者体表心电图对梗塞相关动脉预测的价值。方法:对120例急性心肌梗死患者的心电图与冠脉造影结果进行比较。结果:前间壁、前壁、广泛前壁心肌梗死其左前降支病变阳性率96.6%;下壁心肌梗死其右冠脉病变阳性率83%,左回旋支病变阳性率60%;下后壁心肌梗死其右冠脉病变阳性率89%,左回旋支病变阳性率67%;右室梗死其右冠脉病变阳性率100%;下壁合并右室梗死其右冠脉病变阳性率88%;正后壁梗死3例均显示为三支病变。结论:心肌梗死心电图定位与其相关冠脉病变关系密切,虽然有一定的局限性,仍不失为一项重要的评估方法。

Objective： To explore the predictive Value of surface electrocardiogram （ECG） for infarct-related artery in patients with acute myocardial infarction. Methods： 120 patients with acute myocardial infarction were observed; the results of ECG and coronary angiography were compared. Results： The positive rate of left anterior descending lesion was 96. 6% in antero-septal wall, anterior wall and extensive anterior wall myocardial infarction ; the positive rate of right coronary artery and left circumflex artery lesions were 83% and 60% in inferior wall myocardial infarction; the positive rate of right coronary artery and left circumflex artery lesions were 89% and 67% in descending posterior wall myocardial infarction; the positive rate of right Coronary artery lesion was 100% in right ventricular myocardial infarction; the positive rate of right coronary artery lesion was 88% in inferior wall combined with right ventricular myocardial infarction; the positive rate of coronary artery triple vessel lesion was 100% in positive posterior wall myocardial infarctiorL Conclusion： Coronary artery lesion is closely related with the ECG of myocardial infarction. Though this method has certain limitations, but it is an important evaluating method for coronary artery lesion.
