近年来,我们时常听到“某某猝死”这类不算新闻的新闻。所谓猝死是指自然发生的出乎意料的突然死亡。其临床特征主要是突发意识丧失。大动脉搏动消失,在20～30秒的叹息样呼吸后呼吸停止。猝死发生前可能有胸痛、气急,也可能毫无预兆就突然发生。在成人发生的全部猝死中,心脏性猝死占80%以上。 In recent years, we often hear news of such news as “sudden death”. Sudden death refers to the sudden unexpected death that occurs naturally. Its clinical features are mainly the loss of sudden consciousness. Arterial pulse disappeared, breathing stopped after a sigh-like breathing of 20 to 30 seconds. Sudden death may occur before chest pain, shortness of breath, may also happen without warning on the sudden. In all sudden deaths in adults, sudden cardiac death accounts for more than 80%.
