由于体表心电图无创,简单,短时间内即可做出诊断,迄今仍是急性心肌梗死(acu te m yocard ia l in farction,AM I)的最常用诊断方法。结合临床资料,可对70%~80%的AM I做出早期诊断。1心电图诊断AM I分类的演变20世纪80年代以前,将AM I心电图是否出现病理性Q波分为急性透壁性心肌
Since body surface electrocardiography is a non-invasive, simple, and short-term diagnosis, it is by far the most commonly used diagnostic method for acute myocardial infarction (AMI). Combined with clinical data, 70% ~ 80% AM I can make early diagnosis. 1 ECG AM I evolution of the classification before the 1980s, the AM I ECG pathological Q wave is divided into acute transmural myocardium
