当前世界多数国家的死亡率分析结果表明,心脏性猝死严重地威胁着人民的生命,尤以冠心病中的心肌梗塞为最。在美国,每天约有一千多人猝死,每年约有70万人死于冠心病,其中65％是猝死,故比肿瘤的威胁更为严重。现已明确,冠心病的猝死并非冠状动脉硬化必然的不可逆的最终后果,而心室纤颤则是常见的心电不稳定的猝死原因,但此种原因的心室纤颤是可挽救的。在美国有人是将电极插入右心室进行 Mortality analysis in most countries in the world shows that sudden cardiac death seriously threatens the life of the people, especially myocardial infarction in coronary heart disease.
