溶栓治疗尚未开始之前,已对信号平均心电图、放射性核素心室造影及动态心电图在心肌梗塞后患者危险性级别估测中的作用进行过许多研究。本文目的则是评价信号平均心电图、放射性核素心室造影、动态心电图及临床变量分析对大规模溶栓治疗时代的心肌梗塞后患者发生心律失常事件的识别能力。方法:研究对象为1989年8月～1990年7月收入维多利亚皇家医院治疗并已确诊的急性心肌梗塞存活患者,伴有束支传导阻滞、房颤、心源性休克或其它不适于研究的心肌梗塞患者均已排除。共有301例
Much research has been done on the role of signal-averaged ECG, radionuclide ventriculography, and ambulatory electrocardiogram in estimating risk levels in patients after myocardial infarction, before thrombolytic therapy has begun. The purpose of this paper is to evaluate the ability of signal arrhythmia, radionuclide ventriculography, ambulatory electrocardiogram and clinical variables analysis to identify arrhythmic events in patients after myocardial infarction in a thrombolytic therapy era. METHODS: The subjects were survivors of acute myocardial infarction who had been treated in the Royal Victoria Hospital from August 1989 to July 1990, with branching block, atrial fibrillation, cardiogenic shock or other unsuitable for study Patients with myocardial infarction have been ruled out. A total of 301 cases
