急性心肌梗死心电图与冠状动脉造影相关探讨

Relation Between ECG and Coronary Angiography in Acute Myocardial Infarction

目的:探讨心电图对急性心肌梗死和梗死部位的诊断价值。方法:对45例急性心肌梗死的心电图与冠状动脉造影结果进行分析比较。结果:45例急性心肌梗死患者中,冠状动脉造影阳性43例,阴性2例;心电图阳性变化39例,可疑阳性变化6例。心电图梗死部位定位与冠状动脉造影定位相符合率高,达92.31%。结论:心电图对急性心肌梗死及梗死部位定位诊断符合率高,且无创、可重复、简便易行,可作为首选诊断急性心肌梗死的方法。

Objective To in vestigatet relation between ECG and Coronary Angiography inhe diagnosis value of elestrocardiogrmam（ECG） for acute myocardial inrar Ction（AMI） and inrarction location. Methods ECG data were compared and arialyzed in 45 AMI patients with the repotts of coronary anglography （cAe）. Results The positive numbers of CAG were 43 and the negativenumbers were 2 in 45 AMI patients^39 patients had ECG positive changes,6 patients had doubtful positive changes. The coincidental percent（92. 31~）was high for the diagnosis of AMI location, compared ECG with CAG. Conclusion ECG has higher diagnosis coincidental percent for AMI location. It also is a noninvade, repetitiVe,convenience check fnethod,and could be used to diagnose AMI chiefly.
