反复性心室反应是右室程序刺激时常见的一种现象,其对预后的意义尚不明.本文对65例患者进行回顾性研究,旨在明确反复性心室反应的发生率及其对预后的意义.方法:(1)研究对象:65例冠状动脉疾病(47例)和充血性心肌病(18例)患者,其中男49例,女16例,平均年龄55±11岁.26例因室性心动过速(17例)和心室颤动(9例),39例因室内和房室传导障碍及窦房结功能不良而进行电生理研究.试验前各种心脏药物的停用时间为该药的5个半寿期,洋地黄类至少停用1周.(2)电生理研究:将双极电极导管
Recurrent ventricular response is a common phenomenon when right ventricular stimulation, the significance of prognosis is unknown.This retrospective study of 65 patients aimed at identifying the incidence of recurrent ventricular response and its prognostic significance Methods: (1) Subjects: 65 patients with coronary artery disease (47 cases) and congestive cardiomyopathy (18 cases), including 49 males and 16 females, with an average age of 55 ± 11 years. Tachycardia (17 cases) and ventricular fibrillation (9 cases), 39 cases of electrophysiological studies due to room and atrioventricular conduction disorders and dysfunction of the sinus node.A variety of cardiac drugs before the trial of the off-time for the drug 5 half-life, digitalis disabled for at least 1 week. (2) electrophysiological studies: bipolar lead
