Outcome
- Type
- PRIMARY
- Title
- Post-ablation Atrial Fibrillation Recurrence
- Description
Investigators monitored subjects upon discharge, 24-48 hours after AF ablation. This was recorded by either the occurrence of a single positive atrial arrhythmias (AA) ECG reading on a 12-lead ECG, Holter monitor, obtained on the daily event strips from the Preventice monitoring device, or 30-day monitoring patch.
- Time frame
- Up to 56 weeks. From date of ablation until the date of first documented Atrial Fibrillation recurrence, whichever came first, assessed up to 56 weeks.
