根据大量的资料统计急性心肌梗塞的死亡病例中约40—50％是在急性发病后一小时死亡。中年及年龄较轻的死亡病例中63％在发病后一小时内死亡。因此在入院前大多数患者不是死亡就是病情开始恢复。有人总结了248个于发病后一小时内就诊的病例,发现心律不齐的发病率很高。其中75％(185例)在转院前需要治疗,面69％(170例)的治疗是心动过缓、室性心律不齐或室上性心律不齐,其中12例有心衰。在住院后长期连续监察过程中发现约有75％患者出现心律不 According to a large amount of data, about 40-50% of the death cases of acute myocardial infarction are one hour after the acute onset of death. Sixty-three percent of middle-aged and younger deaths die within an hour of onset. Therefore, most patients before admission is not dead or the disease began to recover. It was concluded 248 cases of patients within an hour after onset, found that the incidence of arrhythmia is very high. Among them, 75% (185 cases) needed treatment before the transfer and 69% (170 cases) had bradycardia, ventricular arrhythmias or supraventricular arrhythmias. Twelve of them had heart failure. Long-term continuous monitoring after hospitalization found that about 75% of patients had arrhythmia
