His束起搏可分为直接His束起搏和His束旁起搏,后者较前者易实现。临床研究表明His束起搏有良好的血流动力学效益,对急性或慢性心功能均有益。对部分心力衰竭的病人行His束起搏可使宽的QRS波变窄,改善心功能。但His束起搏是否造成His束损伤及后续的损伤,进而影响左右束支还有待临床观察或研究。 His bundle pacing can be divided into direct His beam pacing and His bundle pacing, the latter is easier to achieve than the former. Clinical studies have shown that there is good hemodynamic benefit of His bundle pacing, both for acute and chronic heart function. His bundle pacing in patients with partial heart failure can narrow the wide QRS wave and improve heart function. However, whether His bundle pacing causes damage to the bundle of the bundle and subsequent damage, and then the left and right bundle branches still need clinical observation or research.
