病态窦房结综合征植入单腔心房起搏器疗效及安全性研究

Efficacy and safety of single chamber atrial pacemaker implantation in patients with sick sinus Syndrome

目的:探讨病态窦房结综合征植入单腔心房起搏器疗效及安全性。方法:随机选取房室传导功能正常的病态窦房结综合征患者120例,分别置入心房起搏器(AAI)60例及双腔起搏器(DDD)60例,所有患者均随访6年。结果:AAI组无高度房室传导阻滞患者出现。相比AAI组,DDD组增加了心房颤动、心力衰竭、脑卒中、全因性死亡风险。结论:房室传导功能正常的SSS患者,选择置入AAI起搏器可能更合适。

Objective To analyse the efficacy and safety of patients with sick sinus syndrome（ SSS） were placed single chamber atrial pacemaker. Method 120 patients of SSS with normal atrioventricular conduction function were randomly placed atrial pacemaker（ AAI） in60 cases and dual chamber pacemaker（ DDD） in 60 cases. All the patients were followed up for 6 years. Results The group AAI was not high degree atrioventricular block patients. Compared with AAI group,DDD group increased atrial fibrillation,heart failure,stroke,all because of the risk of death. Conclusion For normal atrioventricular conduction in patients with SSS,the choice of AAI pacemaker may be more appropriate.
