对急性心肌梗死 (AMI)患者非梗死部位导联 ,尤其是梗死部位对应导联 ST段压低的临床意义的研究颇多 [1～ 3] ,多数认为合并 ST段压低提示梗死范围大 ,预后不良 ;也有少数结果认为代表多血管病变或 ST段压低部位的心肌充盈缺损。但 ST段压低的机制并未完全明确 ,因而有关早期梗
There is a lot of research on the clinical significance of the leads of non-infarction in acute myocardial infarction (AMI) patients, especially the corresponding ST-segment depression in infarcts [1-3]. Most of them think that the combination of ST-segment depression has a large infarct size and poor prognosis ; There are a few results that represent the filling defect of myocardial lesion or ST-segment depression. However, the mechanism of ST-segment depression is not completely clear, and therefore related to the early stem
