摘　　要：目的研究心室自身优先(VIP)功能对减少心室起搏比例的影响。方法 30例病态窦房结综合征患者安装具有VIP功能双腔起搏器,关闭VIP功能2个月,测量心室起搏比例,开启VIP功能2个月,比较不同功能下心室起搏比例。结果关闭VIP功能,心室起搏累计百分比为(78.87±18.73)%;打开VIP功能,心室起搏累计百分比为(12.15±11.22)%;打开VIP功能后的心室起搏百分比明显低于关闭VIP功能后的心室起搏百分比,差异有统计学意义(P<0.05)。结论 VIP功能可有效减少右心室起搏累计百分比。Objective To evaluate the influence of ventricular intrinsic preference （VIP） on reducing ventricular pacing. Methods The pacemaker St Jude 5826 were implanted in 30 patients with sick sinus syndrome, and the VIP were off for 2 months following with being on for another 2 months. The ventricular pacing was recorded. Results There was significant reduction in ventricular pacing rate when VIP was on when comparing with that when VIP off （ 12. 15 ＋ 11.22% vs 78.87 ± 18. 73%, P 〈 0. 05 ）. Conclusion The VIP could significantly reduce right ventricular pacing events.
