摘　　要：目的:观察右心室起搏器术(VVI)与双心腔起搏术(DDD)在Ⅲ度房室传导阻滞老年患者中的疗效。方法:采用回顾性分析,将68例患者分为VVI组和DDD组,比较两组心功能变化、房颤、缺血性脑卒中的发生率。结果:心动超声心功能测定,术前和随访结果比较:VVI组左室射血分数(LVEF)从(53.8±2.1)%下降至(49.5±3.4)%,P<0.05;DDD组LVEF从(54.1±2.6)%下降至(52.7±2.8)%,P>0.05。比较两组患者在心功能变化、房颤的发生率均有统计学差异,缺血性脑卒中的发生率无统计学差异。结论:对Ⅲ度房室传导阻滞老年患者,两种起搏方式的比较,DDD对Ⅲ度房室传导阻滞老年患者心功能的保护及房颤更低发生率均优于VVI组。Objective： To compare the clinical efficacy of VVI pacing and DDD pacing in old patients with third-degree atrioventricular block. Methods：A total of 68 patients with third--degree atrioventricular block were divided into two groups in this retrospective study： VV/pacing （n = 33, male 14, female 19, mean age 72. 7 ± 6. 8 years old） and DDD pacing （n = 35, male 16, female 19, mean age 73.1±6.7 years old）. Efficacy was evaluated by parameters of heart function and the incidence of atrial fibrillation and ischemic stroke. Results：By comparing the Doppler echocardiographic parameters obtained in preoperative and postoperative follow-up periods, left ventricular ejection fraction （LVEF） was decreased from （53.8± 2. 1）% to （49.5 ±3.4） % （P〈0. 05） in VVI pacing; LVEF was decreased from （54. 1 ±2. 6） % to （52. 7 ±2.8） % （P〉 0.05） in DDD pacing as well. In all cases, clinical symptoms were improved. The episodes of atrial fibrillation were of significantly statistic difference （P〈0.05） between the two groups,and those of isehemic stroke were not significantly different（P〉0. 05） between the two groups. Conclusion：DDD pacing in patients with third degree atrioventricular block may be a wise choice.
