Brief summary
This study is a multicenter, prospective, randomized cross-over study to compare His Bundle Pacing (HBP) with Bi-Ventricular Pacing (BiVP) in HF Patients with AF who need atrial-ventricular node ablation.
Detailed description
Patients who meet the inclusion and exclusion criteria will be enrolled into the study. In the study, both atrial-ventricular node(AVN) ablation and Cardiac Resynchronization Therapy (CRT) implantation are performed with HBP lead implanted and connected with the A port of CRT device. Followed with successful AVN ablation, HBP lead and CRT implantation, patients are 1:1 randomized into BiVP and HBP group for 9 months and then crossover for another 9 months. The primary end points of the study is the change of left ventricular ejection fraction (LVEF) in both HBP and BiV pacing group.
Interventions
Bi-ventricular pacing by a CRT device
His-bundle pacing by a CRT device through the pacing lead at His-bundle region
