生理性起搏[1]是指人工心脏起搏器在矫正患者心率的同时通过起搏器不同的类型、起搏方式、电极的位置、各种间期的调节等方法的应用,使起搏节律及血流动力学效果最大程度地接近心脏的正常生理状态。因此心脏起搏时对血流动力学的影响已引起越来越多学者的关注,尤其是起搏部位的
Physiological pacing [1] refers to the artificial heart pacemakers in the correction of heart rate in patients with different types of pacemaker, pacing mode, the location of the electrode, the interphase adjustment and other methods of application, so that pacing Rhythm and hemodynamic effects are as close as possible to the normal physiological state of the heart. Therefore, the effect of cardiac pacing on hemodynamics has attracted more and more scholars attention, especially pacing site
