TEMPOROSPATIAL DISPERSION IS RARELY SEEN IN PATIENTS UNDERGOING RADIOFREQUENCY ABLATION FOR PERSISTENT ATRIAL FIBRILLATION AND IS NOT ASSOCIATED WITH AF TERMINATION: A PILOT STUDY

Ablation of persistent atrial fibrillation (pAF) is suboptimal. Seitz et al reported a novel observation of targeting areas of temporospatial dispersion (TSD) which are thought to represent focal drivers for paroxysmal and pAF. TSD regions are described as clusters of electrograms with consistent
