摘　　要：心源性猝死(SCD)具有发病出人意料、病情进展快速和死亡急骤等特点,严重威胁人类的健康。且当今社会SCD的发病率成逐年升高的趋势并已成为重要死亡原因之一。SCD多是在内外因(即病因及诱因)的交互作用下发生的,其中病因多指患者生前体内的潜在性疾病,诱因多指诱发或促使机体潜在性疾病突然向恶性转变的外部因素,二者中病因起主要作用,同时诱因参与SCD的发生发展。目前研究把SCD分为:心律失常型猝死和循环衰竭型猝死。前者较常见,主要是由于致命性快速心律失常所致,且多发生在院外。导致猝死的病因较多,故SCD需要与非心源性猝死相鉴别。由于SCD的发病突然,死亡率高,因此明确其病因、分类及鉴别,对降低SCD的发生率及预防SCD的发生具有重要的临床意义,同时对降低心血管病的死亡率有重要意义。Sudden Cardiac Death（SCD）features in unexpected pathogenesis,rapid disease progression and suddenness of death.Since the incidence of SCD is increasing year by year,it has become one of the major causes of death for mankind.Generally speaking,SCD occurs by interaction of the internal（etiology）and external（incentives）factors.Etiology is the primary reason of SCD.It refers to the deceased body of the underlying disease or lesion.The incentive is to induce or cause the body＇s potential disease suddenly to malignant transformation,resulting in the external factors of the occurrence of SCD.Sudden Cardiac Death is mainly caused by the etiology,but in most cases,the role and participation of incentives also contributed to the occurrence of sudden cardiac death.Currently,SCD can be classified into two types-one is caused by arrhythmia,and the other is caused by circulatory failure.The former is more common,and it frequently occurs outside the hospital caused by serious arrhythmia.Since the etiology of sudden death is various in general,it is quite important to identify SCD with Sudden Non-Cardiac Death（SNCD）.Due to the paroxysm and high mortality of SCD,it is very important to understand the causes and classifications of SCD.Therefore,it contributes to preventing and decreasing the morbidity and mortality of sudden death and cardiovascular disease.
