Which treatments control atrial fibrillation?

Several: There are medications to keep the heart in a normal rhythm after a shock to restore the normal rhythm. It is also possible just to leave the patient in fibrillation and give medication to prevent the heart from beating too rapidly. Either way, anticoagulant drugs such as warfarin or dabigatran might be needed to prevent clots depending on how many risk fractors are present. If not many, aspirin.

It Varies: The most important treatment is stroke prevention, which is usually done by medications (aspirin or warfarin). Sometimes rate control medications are used, like metoprolol. If the af is severe enough, stronger anti-arrhythmic medications are used, like propafenone. If these do not work, catheter ablation may be recommended. Pacemaker and av-node ablation may be used as a last resort.
