老年人心脏性猝死65例临床分析

Clinical analysis of sudden cardiac death in aged patients

目的 探讨老年人心脏性猝死（SCD）的危险因素.方法 对65例老年SCD患者进行心电图、心电监护、Holter、彩色多普勒超声心动图检查、电解质等检测,并与对照组比较.结果 老年人SCD复杂性室性期前收缩、左室收缩功能不全、低血钾症、心脏扩大病例数多于对照组（均P＜0.05）.结论 老年人SCD与复杂性室性期前收缩、左室收缩功能不全、低血钾、心脏扩大相关.

Objective To study the clinical features of aged patients with sudden cardiac death（SCD） for improving the resuscitation rate. Methods Hie usual etiology of SCD,electrocardiogram（ECG）,echocardiography, dynamic electrocardiography（DCG）, X-ray and electrolytes were analyzed. Results Most sudden death had inducement. Electrolytes disorder,ventricular ectopic beats,high grade atrioventricular block, auxocardia, left ventricular hypertrophy, cardiac insufficiency and myocardial ischemia could cause serious arrhythmias （.all P 〈0.05）. Conclusion It could be related to heart functional class,left ventricular enlargement,myocardial ischemia,hypokalemia in aged patients with SCD.
