A single-center, prospective, randomized trial to evaluate the efficacy of ablation using the spatiotemporally distributed potentials visualized by a fractionation map compared with ablation using low-potential regions visualized by a voltage map in patients with recurrent sustained atrial fibrillation (ARCHERY trial).
