Managing Recent-Onset Atrial Fibrillation in the ED

Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance. AF is a risk factor for ischemic stroke and heart failure, both of which represent significant public health problems. With an increasing prevalence among an aging population, symptomatic AF-related ED visits have been rising and will likely continue to rise. Traditionally, ED patients thought to have recent-onset AF have been hospitalized for monitoring and evaluation of more serious conditions. More recently, clinicians have been utilizing a more aggressive approach in which stable ED patients with presumed recent-onset AF are treated with elective cardioversion without anticoagulation. While previous reports suggest that this approach is associated with a high rate of cardioversion to sinus rhythm and a low rate of hospitalization and complications, there is no consensus on whether it is better than traditional approaches. Seeking Confirmation on Recent-Onset AF Treatment In the February 2012 Journal of Emergency Medicine, David R. Vinson, MD, and colleagues published a prospective multicenter study that describes the management of ED patients with presumed recent-onset AF. “It had been our anecdotal experience at three affiliated community EDs that taking an aggressive cardioversion approach to managing patients with recent-onset AF was effective and associated with few complications,” says Dr. Vinson. “In this study, we put our practice patterns under critical scrutiny to confirm the safety and effectiveness of ED cardioversion and to accurately measure the incidence of thromboembolism 30 days after discharge.” “Clinicians who are already practicing a more aggressive approach to restoring sinus rhythm can be reassured by the safety and efficacy that was observed in our study.” Dr. Vinson and colleagues analyzed 206 patients...
