Catheter ablation is a minimally invasive procedure. It destroys the heart tissue that causes atrial fibrillation and that keeps atrial fibrillation going after it starts.
For help deciding whether catheter ablation is a good choice for you, see:
AV node ablation is another type of catheter ablation. It does not stop atrial fibrillation but it can relieve symptoms.
Pacemakers are sometimes needed by people who have atrial fibrillation. The pacemaker does not treat atrial fibrillation itself. The pacemaker is used to treat a slow heart rate (bradycardia) that happens in some people who have atrial fibrillation.
