在临床工作中,诊断心肌梗死主要依靠临床症状、心电图改变和酶学改变三项指标。早期心肌梗死的酶学变化常常在急性心肌梗死发生后4~6h才会升高,因此,急性心肌梗死的超急期诊断就会受到一定限制。而心电图则是早期诊断心肌梗死最敏感的方法,在急性心肌梗死早期,心电图具有特征性
In clinical work, the diagnosis of myocardial infarction depends mainly on clinical symptoms, ECG changes and changes in enzyme three indicators. Enzymatic changes in early myocardial infarction often occur 4 to 6 hours after the onset of acute myocardial infarction. Therefore, the diagnosis of acute myocardial infarction may be limited by the ultra-rapid diagnosis. The ECG is the most sensitive early diagnosis of myocardial infarction method, in the early stages of acute myocardial infarction, ECG has a characteristic
