BACKGROUND Atrial fibrillation (AF) ablation guided by complex fractionated electrograms (CFE) has been described, but the spatial and temporal stability of the electrograms (EGMs) has been questioned. OBJECTIVE The purpose of this study was to prospectively assess the spatial and temporal stability of CFE in patients with persistent AF. METHODS Twenty-four patients were studied. For 12 patients, two high-density CFE maps were performed during AF at baseline (0 minute) and 20 minutes later… CONTINUE READING
