2. Subject has PerAF with no history of prior AF ablation therapy (Phase 3)
3. Subject is 18 to 80 years of age
4. Subject has presence of AF-related symptoms and is scheduled for clinically indicated standard of care AF ablation to manage PerAF (Phase 2 or 3) or long-standing PerAF (Phase 2)
5. Subject is able to provide written informed consent
6. Subject is able and willing to complete all study procedures
