Does His or para-His pacing preserve LVEF and mechanical synchrony compared to RVSP in patients with AVB, narrow QRS, and LVEF > 0.40?
In patients with AV block and preserved ejection fraction, His or para-His pacing better preserves left ventricular function and mechanical synchrony at 12 months compared to right ventricular septal pacing.
His or para-His pacing preserves LVEF and mechanical synchrony as compared with RVSP after 12 months pacing in patients with AVB, narrow QRS, and LVEF > 0.40.
Kronborg et al. (Fri,) studied this question.
