Rotors Detected by Phase Analysis of Filtered Epicardial Atrial Fibrillation Electrograms Colocalize With Regions of Conduction Block

摘要

BackgroundSeveral recent studies suggest rotors detected by phase mapping may act as main drivers of persistent atrial fibrillation. However, the electrophysiological nature of detected rotors remains unclear. We performed a direct, 1:1 comparison between phase and activation time mapping in high-density, epicardial, direct-contact mapping files of human atrial fibrillation.
