非右心室心尖起搏部位的研究进展

Advances in non-right ventricular apical pacing sites

长期右心室心尖部起搏,可能导致心脏电活动及机械收缩不同步,诱发心房颤动和心力衰竭等不良效应。随着技术进步和植入器械改善,目前临床研究热点主要集中在非右心室心尖部起搏部位,希氏束或希氏束旁、右心室流出道间隔部和右心室中位间隔起搏及双心室起搏,因具有相对生理的起搏途径,是目前认为较为理想的起搏位点,有助于改善心功能,防止出现起搏器介导的心力衰竭。

Continued right ventricular apical pacing may lead to unsynchronized cardiac electric activity and mechanical contraction resulting in the undesirable effects, including atrial fibrillation, heart failure. With the technological progress and improvement of implantable tools, current clinical research topics mainly focus on the nonright ventricular apical pacing, including bundle of His pacing, para-hisian pacing, right ventricular outflow tract septum pacing, right ventricular mid-septal pacing and biventricular pacing. Currently, non-right ventricular apical pacing is considered more ideal pacing site due to its relative physiological pacing way and it is helpful to improve cardiac function and prevent pacemaker-mediated heart failure.
