The admission electrocardiogram (ECG) was studied in 898 patients admitted to a coronary care unit over two years. The diagnosis made from this tracing was compared with that made at the end of the patient's stay. About half the cases of recent myocardial infarct were diagnosed from the admission ECG, but accuracy rose to 83% with serial ECG's in the unit. The ECG is important but not entirely reliable in the early detection of acute myocardial infarction, which should be largely a clinical diagnosis.
对两年内入住冠心病监护病房的898例患者的入院心电图进行了研究。将根据该心电图做出的诊断与患者出院时的诊断进行比较。近期心肌梗死病例中约有一半可通过入院心电图诊断出来,但在病房内进行系列心电图检查时,诊断准确率可升至83%。心电图在急性心肌梗死的早期检测中很重要,但并不完全可靠,急性心肌梗死在很大程度上应依靠临床诊断。
