The purpose of this study is to assess how safe VARIPULSE pulsed field ablation (PFA) catheter is and how well it works compared to food and drug administration (FDA) approved FARAWAVE PFA catheter in participants with symptomatic persistent atrial fibrillation (PsAF; continuous irregular, rapid heartbeat that lasts over 7 days and doesn't stop on its own).
Inclusion criteria: * Participant has been diagnosed with symptomatic persistent atrial fibrillation (PsAF), which is defined as continuous atrial fibrillation (AF) sustained beyond 7 days and less than 365 days in duration documented by: i. A physician's note documenting diagnosis of symptomatic PsAF as defined above and ii. Two electrocardiograms showing continuous AF, with electrocardiogram taken at least 7 days apart (electrocardiograms cannot be greater than \[\>\] 365 days prior to enrollment) or iii. A 24-hour arrhythmia monitor documenting continuous AF within the last 365 days * Part…
