Left ventricular systolic time intervals were measured daily during 601 episodes of acute myocardial infarction. The ratio of pre-ejection period to ejection period during the first 24 hours permitted patients to be arranged in six prognostic groups with mortalities while in hospital ranging from 4 to 60 per cent. The only factors completely independent of the systolic time intervals which were shown statistically to be associated with high mortality while in hospital were defects in atrioventricular and intraventricular conduction.
在601例急性心肌梗死发作期间,每天测量左心室收缩时间间期。根据发病后头24小时内心室射血前期与射血期的比值,可将患者分为六个预后组,住院死亡率在4%至60%之间。在统计学上显示与住院高死亡率相关的、完全独立于收缩时间间期的唯一因素是房室传导和室内传导缺陷。
