目的分析心室颤动患者病例的临床特点。方法对2000年至2010年记录到发生心室颤动15例患者的临床资料进行回顾性分析,探讨该病的病因、发病机制及转归。结果 15例中,12例心室颤动致猝死,1例心室颤动持续40s自行终止,2例通过电除颤复律。15例中,1例为扩张型心肌病合并心力衰竭,1例急性脑出血,余13例均为冠心病患者。室颤发生前心电图出现急性ST段抬高10例,急性ST段压低2例,III度房室传导阻滞1例,长QT间期1例,高大U波1例。结论心室颤动是引发猝死的最主要的心律失常,而急性缺血是引发心室颤动的主要因素。
Objective To analyze the clinical characteristics of patients with ventricular fibrillation. Methods The clinical data of 15 patients with ventricular fibrillation recorded from 2000 to 2010 were retrospectively analyzed to explore the etiology, pathogenesis and prognosis of the disease. Results Of the 15 cases, 12 cases of sudden death caused by ventricular fibrillation, 1 case of ventricular fibrillation self-termination of 40s, 2 cases by defibrillation cardioversion. Of the 15 cases, 1 was dilated cardiomyopathy with heart failure and 1 had acute cerebral hemorrhage, and the remaining 13 cases were all patients with coronary heart disease. Atrial fibrillation before electrocardiogram showed acute ST segment elevation in 10 cases, acute ST segment depression in 2 cases, III degree atrioventricular block in 1 case, long QT interval in 1 case, high U wave in 1 case. Conclusions Ventricular fibrillation is the leading cause of sudden cardiac death. Acute ischemia is the main factor that triggers ventricular fibrillation.
