心房按需起搏治疗正常房室传导的病态窦房结综合征117例分析

AAI pacing in patients with sick sinus syndrome and normal atrio-ventricular conduction:Analysis of 117 cases

目的:观察心房按需起搏治疗正常房室传导的病态窦房结综合征(SSS)疗效。方法:回顾性分析117例正常房室传导的SSS患者安装心房按需型起搏器后心功能改变,临床症状变化,房室传导阻滞和房颤发生率,评估心房按需起搏治疗SSS疗效。结果:平均随访(8.6±5.2)年,117例SSS患者手术前后心功能无显著变化,左室射血分数(LVEF)术前为(53.4±6.1)%,术后为(56.1±7.2)%(P>0.05)。术后随访期间有3例发生房室传导阻滞(2.6%),5例发生房颤(4.3%)。所有患者心源性脑缺氧症状均消失。结论:对正常房室传导SSS患者安装心房按需起搏器是一个明智的选择,手术方法简单,疗效确切且并发症少。

Objective：To observe the effects of AAI pacing in patients with sick sinus syndrome and normal atrio-ventricular conduction. Methods：A total of 117 patients with normal atrioventricular conduction and sick sinus syndrome undertaken AAI pacing were included in this retrospective study. Effects were evaluated by parameters of heart function, clinical symptoms and the incidence of atrioventricular block and atrial fibrillation. Results： Neither the heart function nor the dopplar echocardiogram [LVEF （53.4±6. 1） % vs （56. 1 ± 7.2）%, P〉0.05] has changed after （8.6 ± 5.2） years follow-up （P〉0. 05）. During all cases, cardiogenic syncope was in none, atrioventricular block in 3 （2.6% ） and atrial fibrillation in 5 （4.3% ）. Conclusion： AAI pacing for patients with normal atrioventricular conduction and sick sinus syndrome maybe a wise choice. The implantation of atrial demand pacemaker was a simple operation with good clinical outcome, little complications and cheap price.
