Investigators have found that attempts at rate and rhythm control among ED patients with complex atrial fibrillation (AF) or flutter appear to substantially increase the rate of adverse events when compared with not making such attempts. The adverse event rate for patients with attempted rate control for AF was 40.7%, compared with a rate of only 7.1% for those not managed with rate or rhythm control.
