心性猝死(SCD)系指由于心脏病引起的突然和意外死亡。多数认为猝死是指出现症状立即死亡(称为瞬间死亡)或6小时内死亡者。近年由于心电生理及生化学研究等的进步,对心性猝死发病机理的了解更加深刻,有关抢救工作亦日趋标准 Sudden cardiac death (SCD) refers to sudden and unexpected death due to heart disease. Most consider sudden death to be symptoms of immediate death (known as instant death) or within 6 hours of death. In recent years due to advances in electrophysiological and biochemical research, understanding of the pathogenesis of sudden cardiac death is more profound, the rescue work is also increasingly standard
