【摘要】 观察右房左室起搏对充血性心力衰竭 (CHF)患者急性血流动力学的影响。 8例心功能II～IV级CHF患者 ,分别置入右房、右室和左室电极 (经冠状静脉窦 ) ,行不同部位组合起搏的急性血流动力学研究 ,其中 6例获得成功。使用Bitronic公司生产的双腔起搏分析仪 (ERA30 0 )分别行单纯右室心尖部 (RVA)、右房右室 (RA +RV)、右房左室 (RA +LV)、右房双室 (RA +BiV)起搏 ,同时用二维超声心动图测定上述四种起搏状况下的血流动力学参数 ,并进行比较。结果 :右房左室起搏和右房双室起搏血流动力学参数两者间无显著差异 ,但比单纯右室心尖部起搏和右房右室起搏有所改善。结论 :右房左室起搏似可使更多的CHF患者在得益于起搏治疗的同时明显降低医疗费用。更多还原

【Abstract】 To observe the changes of acute hemodynamic in right atrial-left ventricular pacing in patients with congestive heart failure (CHF). 8 patients,with heart function II～IV,were implanted with right atrial,right ventricular and left ventricular leads performed by coronary sinus respectively to have acute hemodynamic research of pacing in different sites. 6 cases had been completed successfully. Right ventricular apical,right atrial-right ventricular,right atrial-left ventricular and right atrial-biventricular pacing were performed respectively by dual pacing analyzer (ERA300) made by Bitronic company. Hemodynamic parameters were measured by echocardiography simultaneously. Results: No significance was found between right atrial-left ventricular pacing and right atrial-biventricular pacing,but they were better compared with right ventricular apical pacing and right atrial-right ventricular pacing. Conclusions: Primary results showed that right atrial-left ventricular pacing may make more patients with CHF benefit from pacing therapy and significantly reduce medical cost simultaneously.更多还原
