目的比较右心室间隔部与右心室心尖部起搏对血流动力学的影响。
Objective To compare the hemodynamic changes of right ventricular septal pacing with traditional right ventricular apical pacing.
结论：与常规的右心室心尖部起搏比较，右心室间隔部起搏同样安全，操作简单易行。
Conclusion: Compared with right ventricular apex pacing, right ventricular septal pacing is clinically feasible and safe.
目的以右心室心尖部起搏为参照，评估右心室间隔部起搏的双心室电同步性和血流动力学效应。
Abstract :Objective To evaluate the biventricular electrical synchronism and hemodynamics in the right ventricular septum (RVS) pacing compared with traditional right ventricular apex (RVA) pacing.
