一、基本概念目前对猝死的认识尚不一致。一般系指患者无心衰和休克,或心衰和休克已被控制,一般情况尚好而突然发生的心跳、呼吸骤停,若抢救无效,常在3小时内死亡。Mewhinney认为,猝死系指从症状出现一小时内发生的不可预测的死亡。Fulton等则把从症状出现一小时内发生的死亡称“急死、,而对症状出现24小时内发生的死亡称“早期死亡”。Paul认为猝死系从症状出现24小时内瞬间发生的不易预测的死亡。由此可见,目前对冠心病猝死(包括心肌梗塞后猝死)亦无统一的定义。二、心肌梗塞后猝死的有关问题 (一)心肌梗塞后猝死的严重性:近年来由于 First, the basic concepts At present, the understanding of sudden death is not consistent. Generally refers to patients without heart failure and shock, or heart failure and shock have been controlled, the general situation is still good and sudden heartbeat, respiratory arrest, if the rescue is invalid, often within 3 hours of death. Mewhinney believes that sudden death refers to the unpredictable death that occurs within one hour of the onset of symptoms. Fulton et al. Called “early death” of deaths occurring within an hour from the onset of symptoms and “early deaths” of deaths occurring within 24 hours of onset of symptoms.Paul said that sudden death was transient and difficult to predict within 24 hours of the onset of symptoms Death.Therefore, the current sudden death of coronary heart disease (including sudden death after myocardial infarction) there is no uniform definition .Second, the problem of sudden death after myocardial infarction (A) the severity of sudden death after myocardial infarction: In recent years due to
