摘　　要：目的:观察心室按需起搏器(VVI)与房室顺序生理性起搏器(DDD)对过缓性心律失常治疗的远期疗效。方法:过缓性心律失常患者203例,按不同起搏方式分为心室按需起搏组(141例)与房室顺序生理性起搏组(62例)。研究终点:①在每次预定的随访中,以标准12导联心电图,动态心电图及心电监护诊断房颤;②卒中;③心力衰竭;④死亡。患者出院后1、3、6个月定期随访,以后每隔半年随访一次,分析起搏和感知功能。每例患者至少有一份ECG,部分患者做Holter,了解有无术后阵发性及持续性房颤的发生,对已形成AF患者行心脏多普勒检查以了解有无左心房附壁血栓形成。结果:VVI组与DDD组比较,房颤发生率分别为47例(33.33%)与3例(4.84%),有显著统计学差异(P<0.05)。心衰发生率分别为17例(12.06%)和1例(1.62%),有显著统计学差异(P<0.05)。VVI组脑栓塞发生3例,DDD组无发生;VVI组死亡4例,DDD组死亡1例。结论:双腔起博(DDD)可有效减少房颤与心衰的发生。Objective：To compare the clinical effects of using WI or DDD in patients with bradycardia arrhythmia. Methods ： 203 patients with bradycardia arrhythmia were divided into VVI（ n = 141）and DDD group（ n = 62）. Endpoint of this study included（1） that 12-lead ECG and Holter at every follow-up were performed to diagnose onset of atrial fibrillation（AF） ; （2）stroke; （3）heart failure; （4）cardiovascular death. Each patient was followed-up 1,3 and 6 months after discharged from the hospital for evaluating the effects. After that, the follow-up was carried out at interval of every half year. Also, ECG recording for each subject was kept, besides Holter and UCG, for comparing those with AF. Results ： The incidence of atrial fibrillation in VVI group was observed in 47 subjects（33.33% ） vs . 3（4.84% ） in DDD group, and 17 and 1 patients were complicated with heart failure in VVI group and DDD group, respectively, which was significantly different （ P 〈 0.05）. Stroke was found in 3 patients in VVI group, while it was not seen in DDD group. There were 4 deaths in VVI group and 1 death in DDD group. Conclusion： In bradycardia arrhythmia, dual-chamber pacing can effectively reduce the incidence of atrial fibrillation and heart failure.
