我院自1971～1981年收治急性心肌梗塞491例,其中并发心律失常375例占76.4％。在这375例中,快速心律失常237例占63.2％,缓慢心律失常62例占16.5％,束支传导阻滞76例占20.3％。通过心电示波监测,心律失常发生时间以梗塞后24小时最多,特别是在梗塞后4小时内有50%病例出现心律失常,其中以频繁室性早搏、窦性心动过速、房室传导阻滞,心房性心律失常,窦性心动过缓最多见。在治疗中除了加强 491 cases of acute myocardial infarction were admitted to our hospital from 1971 to 1981, of which 375 cases were complicated by arrhythmia, accounting for 76.4%. Of the 375 patients, 237 were tachyarrhythmia, 63.2% were bradyarrhythmia, 62.5% were bradyarrhythmia, and 76.3% were bundle branch block. By ECG monitoring, arrhythmia occurred at 24 hours after infarction, especially within 4 hours after infarction, 50% of cases arrhythmia, including frequent ventricular premature beats, sinus tachycardia, atrioventricular conduction Blocking, atrial arrhythmia, sinus bradycardia most common.
