目的 观察双腔起搏器自动房室间期搜索功能(AV Search)减少心室起搏的有效性及对血流动力学和快速房性心律失常的影响.方法 对两种DDD/R起搏器97例(有AV Search功能47例,无AV Search功能50例)患者术后半年内随访观察.结果 有AV Search功能组术后1、3、6个月右心室起搏百分比明显小于无AV Search功能组[(19.2±5.6)%vs(80.4±10.2)%,(17.8±6.6)%vs(75.3±9.5)%,(17.4±7.3)%VS[76.2±8.6]%,P<0.05].有AV Search功能组心脏指数、每搏量、左心室舒张末内径、左心房内径及患者心功能分级均无明显改善(P>0.05);而左心窒射血分数则高于无AV Search功能组(P<0.05).高频心房事件也显著减少((31±9)vs(49±11),P<0.05].结论 有AV Search功能DDD/R双腔起搏器在减少非必须的心室起搏,改善血流动力学,减少高频心房事件方面优于与无AV Search功能DDD/R起搏器.

Objective To observe the effects of dual-chamber pacemaker atrioventricular interval auto matic search function(AV Search function)on hemodynamic parameters and reducing ventricular pacing and at rial high rate events. Methods Ninty-seven patients implanted with two types of DDD/R pacemakers (AV Search 47 cases,non AV Search 50 cases) were investigated in six months of follow-up study. Results Patients implanted with AV Search DDD/R had a significant decrease in percentage of ventricular pacing 1,3 and 6 months after implant[(19. 2 ±5. 6)% vs. (80.4 ± 10. 2)%,(17. 8 ±6. 6)% vs. (75. 3 ±9. 5)%, (17. 4 ± 7. 3) % vs. (76. 2 ± 8. 6) %, P < 0. 05]. The LVEF was increase in AV Search group (P < 0.05) although hemodynamic parameters, CI, SV, LVEDD, LAD and cardiac function show no significant changes. The atrial high rate events were significantly decreased in AV Search group (31 ±9 vs. 49 ±11, P <0. 05). Conclusion DDD/R with AV Search is superior to non AV Search DDD/R in reducing unnecessary ventricular pacing, atrial high rate events,and improving hemodynamics.
