Patients with permanent atrial arrhythmia with an indication of cardiac pacing and atrioventricular junction ablation will be prospectively enrolled.~They will undergo the implantation of a single-chamber pacemaker with left bundle branch area pacing confirmed according to electrocardiographic parameters. Atrioventricular node ablation will be performed the following day through a femoral venous approach.~Perioperative data and potential complications will be collected. Patients will be prospectively followed during 6 months. They will have clinical examination, 12-lead ECG, and an echocardiography.
Permanent ventricular pacing may be complicated with ventricular dyssynchrony and subsequent pacing-induced cardiomyopathy. We hypothesized that left bundle branch area pacing may prevent the development of pacing-induced cardiomyopathy in patients with permanent atrial fibrillation requiring permanent ventricular pacing.~Patients with permanent atrial arrhythmia with an indication of cardiac pacing and atrioventricular junction ablation will be prospectively enrolled.~They will undergo the implantation of a single-chamber pacemaker with left bundle branch area pacing, and then atrioventricular junction ablation.~They will be prospectively followed during 6 months.
