FDA Approves AF Suppression Device

FDA has approved what St. Jude Medical (St. Paul, MN) calls the first U.S. heart failure device to suppress atrial fibrillation (AF). The device, called the Atlas II + HF cardiac resynchronization therapy defibrillator, has a special algorithm that helps control the heart's atrial rhythm. It does this by pacing slightly faster than the patient's natural heart rate, according to the company.

Nearly 5 million Americans experience heart failure and about 40% of patients who have heart failure also have AF, cites St. Jude in a news release.
