Atrial fibrillation is a common comorbidity in patients with symptomatic heart failure and can be a challenging arrhythmic disorder to treat in the long term. Ablation of the atrioventricular junction and pacing therapy can provide relief to the most highly symptomatic patients. Recent reports, however, have indicated that chronic right-ventricular pacing could cause or aggravate symptoms of heart failure following ablation of the atrioventricular junction.1, 2 To address this issue, studies have assessed the efficacy of cardiac resynchronization therapy in heart failure patients who have atrial fibrillation and atrioventricular junction ablation.
