His-purkinje system pacing improves cardiac performances in
patients with AF
To date, the majority of randomized controlled trials and recommendation
of current guidelines for CRT upgrades focus on the patients with PICM
and sinus rhythm. The biventricular pacing upgrade is still not the
optimal recommendation (IIb) in recent guidelines. The efficacy of CRT
upgrade was unfavorable in patients with AF due to the potential reduces
of biventricular pacing percentage [16,17]. Quite different with
those study, In our study, 62% patients were AF and they had similar
clinical responses with the patients with sinus rhythm. For the patients
dependent on ventricular pacing, HBP would be the optimal choice? We
still need more evidence in future studies.
