Abstract
To assess the hemodynamic effects of right ventricular septal pacing in patients with severe chronic heart failure, we studied 13 patients during intrinsic rhythm and with pacing in the VDD mode at atrioventricular delays of 100 to 200 ms. There was no improvement of any hemodynamic parameter measured with pacing, even in the subgroup of patients with prolonged PR intervals.
摘要
为评估右心室间隔起搏对严重慢性心力衰竭患者的血流动力学影响，我们研究了13例患者，分别在自身心律以及以100至200毫秒的房室延迟进行VDD模式起搏时进行观察。起搏时所测量的任何血流动力学参数均未得到改善，即使在PR间期延长的患者亚组中也是如此。
