Paroxysmal Atrial Fibrillation: What to Do When Initial Rhythm Control Has Not Maintained Sinus Rhythm
Clinical Scenario
Paroxysmal atrial fibrillation — episodes that terminate spontaneously within 7 days or with the assistance of an intervention — in which initial rhythm control therapy has not achieved the defined treatment goals.
Prior Treatment & Reason for Escalation
Initial management centred on rhythm control, employing antiarrhythmic drug therapy (selected according to the underlying cardiac status) or catheter ablation as a first-line option. The defined goals — maintenance of sinus rhythm and reduction of AF-related symptoms — were not achieved, warranting a structured next step.
Next-Line Approach (Partial Overview)
When AF symptoms recur after prior therapy, the next step involves ablation-based strategies — with the specific pathway determined by what has already been attempted. The full protocol details the complete structured regimen.
Clinical Goal
Maintenance of sinus rhythm and reduction of AF-related symptoms.

- Catheter ablation is recommended in patients with paroxysmal or persistent AF resistant or intolerant to antiarrhythmic drug therapy to reduce symptoms, recurrence, and progression of AF.
- Repeat AF catheter ablation should be considered in patients with AF recurrence after initial catheter ablation, provided the patient's symptoms were improved after the initial PVI or after failed initial PVI, to reduce symptoms, recurrence, and progression of AF.
