FAP Maps of the Left Atrium and PVs Before and After Left Atrial GP Ablation (Without PV Isolation or Other Ablation) (Top) Left atrium and PV before left atrial GP ablation; (bottom) left atrium and PV after left atrial GP ablation. An automated algorithm was programmed to identify segments between electrogram peaks of 15 to 80 ms in duration and define fractionated atrial potential (FAP) as those demonstrating more than 40 such segments per 2.5 s. After ganglionated plexi (GP) ablation, there was a marked decrease in the area of FAP, represented by the red area. PA = posterior anterior; PV = pulmonary vein; RAO = right anterior oblique.
