作者用24小时Holter动态心电图,对急性心肌梗塞后第一窦室性心律失常的发病率,进行了前瞻性研究。作试验的108例患者中,有74例进行了12个月的研究。在80％的患者中观察到了室性早搏,这种心律失常占总检查时数的57％小时。将“有意义”的室性心律失常规定为:每10次心搏中有1次以上的室性早搏、多源性室性早搏、二联律或三联律、早搏连发(连 The authors used a 24-hour Holter Holter to investigate the incidence of first sinus arrhythmias after acute myocardial infarction. Of the 108 patients tested, 74 were studied for 12 months. Ventricular premature beats were observed in 80% of patients, accounting for 57% of the total hours examined. The “meaningful” ventricular arrhythmias are defined as: every 10 beats in more than 1 times of premature ventricular contractions, multi-source premature ventricular contractions, bipartite or triple law, premature beats
