目的总结患者住院期间心脏性猝死前的心电图特征,以预警心脏性猝死,尽可能降低猝死的发生率。方法回顾性分析36例住院患者心脏性猝死前的心电图。结果住院患者心脏性猝死的病因以冠心病最多(55.56%),猝死前心电图异常率100%,两种以上异常率86%,三种以上异常率75%,其中以ST-T改变为主。结论对于器质性心脏病住院患者心电图异常率高者,应积极治疗原发病,去除诱因,有望降低心脏性猝死的发生率。
Objective To summarize the electrocardiographic features of patients with sudden cardiac death during hospitalization in order to prevent sudden cardiac death and minimize the incidence of sudden death. Methods The ECG of 36 inpatients with sudden cardiac death was retrospectively analyzed. Results The causes of sudden cardiac death in hospitalized patients were mostly coronary heart disease (55.56%), abnormal ECG before sudden death 100%, more than two abnormalities 86% and more than three abnormalities 75%, especially ST-T changes. Conclusion For patients with organic heart disease, the abnormal rate of electrocardiogram should be actively treated in patients with primary disease and removal of incentives, and it is expected to reduce the incidence of sudden cardiac death.
