In patients with persistent atrial fibrillation recurrence after atrial fibrillation ablation without pulmonary venous reconduction, we evaluated the effectiveness of ablation using spatiotemporal dispersion electrograms (STDE) visualized using a fractionation map. A single-center prospective randomized study evaluating the low voltage zone (LVZ) visualized by voltage map compared to ablation (ARCHERY study)
