Conclusion
In this retrospective, single-center study, patients who presented with atrial fibrillation for more than 48 hours after a TEE negative for an atrial clot, and who were cardioverted in the ED had a significantly decreased time to cardioversion and decreased length of hospital stay when compared to those cardioverted in the cardiological department. There was no significant difference in complications or 30-day readmission rates for either group. This clinical pathway may be implemented in ED observation units. Prospective randomized controlled trials should be conducted to determine the applicability and cost-effectiveness of such a clinical pathway in other ED settings.
