How is atrial fibrillation treated?

Aspirin and warfarin are two medications currently used. They interfere with blood clotting, thus helping to reduce stroke risk in people with atrial fibrillation. A nationwide study reported in December 1996 found that less than 40 percent of patients with atrial fibrillation were taking warfarin. Anticoagulants are also given to people who have atrial fibrillation.
