急性心肌梗塞(AMI)是国家发达居民的主要死亡原因;我国北方一些城市该病住院人数也迅速增长。严重威胁着患者生命与人群健康。做为AMI主要死因的心力哀竭、休克和严重心律失常,与心肌梗塞范围密切相关。近年来,一些学者,提出用心电图(ECG)QRS记分系统估价心肌梗塞范围有较好的敏感性和特异性,并与解剖学直接相关。本文观察了AMI时QRS记分与磷酸肌酸激酶(CPK)及 Acute myocardial infarction (AMI) is the leading cause of death for the country’s well-developed residents; the number of hospitalizations for this disease has also risen rapidly in some cities in northern China. Serious threat to the lives of patients and population health. Heart failure, shock and severe arrhythmia, which are the leading causes of AMI, are closely related to the extent of myocardial infarction. In recent years, some scholars have proposed to use the ECG QRS scoring system to estimate the extent of myocardial infarction has a good sensitivity and specificity, and is directly related to anatomy. In this paper, QRS score and phosphocreatine kinase (CPK) and AMI were observed
