This study is comparing three different ways of doing an ablation procedure for people with persistent atrial fibrillation. Patients will not know which procedure they receive. Patients are then followed by study staff at 3,6, 9, 12, and 18 months. At each of these visits, patients will wear a 24 hour cardiac monitor which will be reviewed with the doctor. Patients will also use a Kardia device which connects to their smartphone, sending weekly transmissions to study staff.
