目的观察心室起搏管理(Managing Ventricular Pacing,MVP)功能减少心室起搏百分比的效果。方法选择因病态窦房结综合征或房室阻滞而植入具有MVP功能的美敦力Adapta系列起搏器的患者共50例,分别程控为DDD模式和MVP模式,3个月后交叉程控为MVP模式和DDD模式,再随访3个月。结果两组患者DDD模式期间心室起搏百分比分别为40.5%(1.3%～90.1%)和39.9%(1.0～91.6%),两组患者MVP模式期间心室起搏百分比分别为5.8%(0～40.2%)和6.4%(0～32.4%)。MVP模式期间的心室起搏百分比明显低于DDD模式期间(p<0.05)。结论 MVP起搏模式能够降低因病态窦房结综合征或房室阻滞行永久性双腔人工心脏起搏器治疗患者的心室起搏百分比。
Objective To observe the effect of Managing Ventricular Pacing (MVP) on reducing the percentage of ventricular pacing. Methods A total of 50 patients with Medtronic Adapta series pacemaker implanted with sick-heart sinoatrial node syndrome or atrioventricular block were enrolled in this study. They were programmed for DDD mode and MVP mode, respectively. Mode and DDD mode, followed by 3 months. Results The percentage of ventricular pacing during DDD mode was 40.5% (1.3% -90.1%) and 39.9% (1.0-91.6%) in both groups. The percentage of ventricular pacing during MVP mode was 5.8% (0-40.2% %) And 6.4% (0 ~ 32.4%). The percentage of ventricular pacing during MVP mode was significantly lower than during DDD mode (p <0.05). Conclusions MVP pacing mode can reduce the percentage of ventricular pacing in patients treated with permanent dual chamber artificial pacemaker for sick sinus syndrome or atrioventricular block.
