FLOW EVAL-AF: FLOW Mapping Electrogram VALidation in Patients With Persistent Atrial Fibrillation

"Subjects will receive ElectroGraphic Flow™ (EGF) mapping with Ablamap® Software and a commercially available 64-pole basket mapping catheter (FIRMap™ Catheter, Abbott Laboratories, Abbott park, IL). The FIRMap™ catheter will be inserted into the right and left atrium to acquire 1 minute recordings of electrical signals in several standardized positions, and turn these into electrographic flow (EGF) maps.~Subjects will receive concomitant high density (HD) electroanatomical mapping of these regions with the commercially available Ensite Precision mapping system and Advisor™ HD Grid mapping catheter (Abbott Laboratories, Abbott Park, IL)."
