The treatment for A-fib depends on how often you have symptoms, their severity and whether you already have heart disease. People who have A-fib but don’t have symptoms may still need treatment.
When A-fib is caused by an underlying risk factor, your doctor may prescribe lifestyle changes, including diet or exercise. Your doctor may also prescribe medications to treat high cholesterol, high blood pressure or thyroid disease.
In some cases, you may need a procedure to implant a medical device, such as a pacemaker, or have surgery, such as open-heart surgery.
