Thirty-Day and 1-Year Outcomes of Emergency Department Patients With Atrial Fibrillation and No Acute Underlying Medical Cause

In this large cohort of ED patients with atrial fibrillation and no acute underlying medical cause, the 30-day rate for stroke or death was less than 1%. Nearly 85% of patients-regardless of treatment approach or conversion to sinus rhythm-were discharged at the index ED visit, and none of these patients had a stroke or died at 30 days.
