急性心肌梗塞病人的不典型心电图表现是急性心肌梗塞漏诊的主要原因之一。多数不典型心电图改变的心肌梗塞病人,其梗塞范围较小,深度较浅,呈小范围的心内膜下心肌梗塞。有人报道,这种心肌梗塞病死率比具有典型心电图表现的心肌梗塞病例高出二倍以上,其主要原因为漏诊或误诊,病人得不到及时而严格的休息和治疗。因此,提高对心肌梗塞不典型心电图改变的认识,对改善预后,降低病死率是具有十分重要的临床意义。
Atypical electrocardiogram in patients with acute myocardial infarction is one of the main causes of missed diagnosis of acute myocardial infarction. The majority of patients with atypical ECG changes in myocardial infarction, the infarct size smaller, shallow depth, showed a small range of subendocardial myocardial infarction. It has been reported that this myocardial infarction mortality than the typical ECG of myocardial infarction cases more than twice as much, mainly due to missed diagnosis or misdiagnosis, patients without timely and strict rest and treatment. Therefore, raising awareness of atypical ECG changes in myocardial infarction, to improve the prognosis and reduce the mortality is of great clinical significance.
