A multicenter report by Stiell et al that prospectively evaluated management and 30-day outcomes in 1091 emergency department (ED) patients with recent-onset atrial fibrillation (84.7%) or atrial flutter (15.3%) found that oral anticoagulants were underprescribed and that patients discharged from the ED in sinus rhythm had a smaller likelihood of experiencing an adverse event. [9]  More than 10% of all patients had adverse events within 30 days, including one case of stroke, but no deaths were reported. Potential risk factors for adverse events included longer duration from arrhythmia onset, radiographic evidence of pulmonary congestion, previous history of stroke/transient ischemic attack, and ED discharge without being in sinus rhythm.
