心脏性猝死的原因性疾病有缺血性心脏病、心肌病、各种原因的心功能不全、瓣膜病、先天性心脏病、预激综合征、QT 延长综合征和心脏肿瘤等。对这些原因性疾病本身的治疗是十分重要的。根据病理解剖结果,缺血性心脏病和高血压引起的猝死所占比例最大;因此预防猝死首先应是通过定期的健康检查早期诊断,并按各个疾病进行生活指导,去除危险因素等。但是也有的心脏猝死原因完全不清楚,有些即使 Causes of sudden cardiac death are ischemic heart disease, cardiomyopathy, heart failure of various causes, valvular disease, congenital heart disease, pre-excitation syndrome, QT prolongation syndrome and cardiac tumors. The treatment of these causes of disease itself is very important.

However, some of the causes of sudden cardiac death are completely unclear, some even if
