摘要 目的观察双腔起搏(DDD)患者不同起搏方式时最佳房室延迟(AVD)的差异。方法对20例置入DDD起搏器的患者经左侧锁骨下静脉插入Swan-Ganz导管,分别测量DDD方式及心房感知心室起搏(VDD)方式下的不同AVD起搏的急性血流动力学效应。结果DDD右心耳起搏优化AVD(149±15ms)比VDD起搏AVD(114±12ms)延长了38±12ms,差异有非常显著性意义(P<0.01)。结论双腔起搏时DDD右心耳起搏可使AVD达到最优。 Objective To investigate optimal atrioventricular delay(AVD) in different pacing modes in patients with dual-chamber (DDD) pacemaker. Methods Acute hemodynamic parameters were measured with Swan-Ganz catheter at varied AVD in DDD and VDD modes in 20 patients. Results Optimal AVD was 149±15ms in DDD fight atrial appendage pacing mode and significantly higher than 114±12ms in VDD pacing mode (P〈0.01). Conclusion DDD right atrial appendage pacing mode makes AVD optimization.
