Arrhythmias & electrophysiology
Paroxysmal atrial fibrillation history is associated with earlier recurrence after first cardioversion compared with primary persistent atrial fibrillation
Authors' conclusion
Patients with primary psAF may have a more sustained response to DCCV compared with those with a preceding history of pAF.
Study context
- Population
- Patients undergoing first direct current cardioversion (DCCV) for persistent AF at a Veterans Affairs centre81.6% primary persistent atrial fibrillation (psAF)
- Participants
- 565 patients
- Exposure
- Prior paroxysmal AF vs primary persistent AF
- Outcome
- AF recurrence after DCCV
- Follow-up
- ECG at 1 and 3 months
Methodological detailssingle-centre, Veterans Affairs centre
