Abstract
Objective To compare the effects on henodynamics of acute or chronic patients by the pacing in right ventricular septum and in right ventricular apex. Methods Eighty advanced A - V block patients were randomly divided into two groups ( with each group 40 cases respectively ), in which one group received RVS pacing while the other group received RVA pacing. The intraoperative hemodynamic parameters and heart function, including ventricular pacing rate, wave width of QRS, were compared between the two groups. Results There were no statistical differences in operation time, X - ray exposure time, intraoperative threshold voltage and the level of perception resistance between the two groups ( P > 0. 05 ). While during operation , there were statistical differences in the stroke volume of acute phase, cardiac index, stroke volume and wedge pressure of average pulmonary artery. ( P < 0. 05 ). Comparing the 12 months follow — up of the two groups of patients, there were statistical differences in the fraction of left ventricular ejection, E/A, QRS wave width and six minutes of walking distance ( P <0. 05 ). Conclusion RVS pacing is as safe and efficient as RVA pacing, while RVS pacing is more beneficial to the hemodynamic and brings less negative effect to heart function.关键词
