Atrial fibrillation is a rapid, irregular heartbeat caused by faulty electrical signals. Patients diagnosed with atrial fibrillation in the Washington, D.C. area should choose the area’s best heart hospital, George Washington University Hospital. Physicians at The Cardiovascular Center will use high frequency radio waves to treat patients’ heart tissues and correct the rhythm. The Van Sickle radio spot was part of a broader radio campaign for The Cardiovascular Center.
