摘　　要：目的:比较心室起搏管理(managed ventricular pacing,MVP)和自动房室搜索+(SearchA V+)2种算法减少因病窦综合征植入起搏器患者心室起搏比例的效能。方法:46例因病窦综合征植入起搏器患者随机分为MVP组18例和Search AV+组28例,分别植入ADAPTA起搏器和EnPulse起搏器。ADAPTA起搏器启用MVP模式,EnPulse起搏器启用DDD/R模式及Search AV+功能。植入起搏器1个月后比较心房、心室起搏比例。结果:MVP组较Search AV+组心室起搏比例中位数显著减少(0.3%vs3.1%,P<0.01),心房起搏比例差异无统计学意义(P>0.05)。结论:因病窦综合征植入起搏器患者应用MVP算法较Search AV+算法可进一步减少心室起搏。Objective：To examine the different abilities to reduce the percentage of ventricular pacing（VP） in patients of sick sinus syndrome,who planted pacemaker between two algorithms,and managed ventricular pacing（MVP） and search atria ventricle（Search AV）＋.Methods：Patients with sick sinus syndrome after pacemaker implantation were randomly divided into the MVP group and Search AV＋ group.The percentages of atrial and ventricular pacing were compared in patients one month after planting pacemaker.Results：The median percentage of VP was significantly lower in MVP group than that of Search AV＋ group（0.3% vs 3.1%,P 0.01）.There was no significant difference in the percentage of atrial pacing between two groups（P 0.05）.Conclusion：Compared with Search AV＋,the managed ventricular pacing algorithm offers further %VP reduction in patients of sick sinus syndrome with a dual-chamber pacemaker.
