摘要 目的:通过前瞻性研究评价病态窦房结综合征(病窦)患者房室传导情况的长期随访观察。方法:168例病窦患者房室传导功能正常,74例植入单腔心房起搏器(AAI),94例植入单腔心室起搏器(VVI),随访期从植入后3个月开始,每年一次测量心电图PR间期。在AAI组,以100~120次/min起搏频率起搏后测量起搏峰至R波起点距离(Stim-R120),平均随访4.5±2.2年。结果:在AAI组,PR间期Stim-R100、Stim-R120及房室结文氏点无变化,仅1例病人发生了Ⅲ°房室传导阻滞而改为VVI起搏(0.2%/年)。结论:房室传导功能在病窦患者长期随访中是稳定的,AAI起搏是安全可靠的,无束支传导阻滞病窦患者可选用。
