Post-procedure Care and Follow-up
Antiarrhythmic medications were continued for at least 3 months to prevent any early recurrences. A clinical interview, surface ECG, and 24-h Holter monitoring were performed 1 day after the procedure and repeated 1, 3, 6 and 12 months after the catheter ablation. AF/AT recurrence was defined as sustained AF/AT lasting more than 30s, which occurred more than 3 months after the catheter ablation.17
