【摘要】 作者对36例平均病期40月的陈旧性心肌梗塞患者进行了随访,有38.9％患者在急性期有左室功能衰竭,而在慢性期心功能大多数维持原状,少数有改善或恶化。心律失常发生率无论在急性期或慢性期可能与心室功能有关。经收缩时间和R_p、△R_p测定显示陈旧性心肌梗塞患者与同年龄正常人相比有某种程度的左室功能障碍。更多还原

【Abstract】 Thirty-six patients with old myocardial infarction (OMI) were studied for 40 months in average after attack. Acute left ventricular failure occurred during acute stage in 38.9％; however, in many cases the cardiac function became stabilized in the chronic stage. In both acute or chronic stages, the incidence of arrhythmias appeared to be related to cardiac function (P<0.01). Ventricular premature beats were very commonly found. A-V block in 8 cases of inferior myocardial infarction was only transient during the acute stage. Examination of systolic time intervals (STIs), Rp and △Rp showed some impairment in the left ventricular function in OMI patients. Examination of cardiac autonomic nervous function suggested that the autonomic dysfunction and development of arrhythmias in OMI patients might be related.更多还原
