Topics in the Best Available Evidence section must be relevant to emergency physicians, are formally peer reviewed, and must have a sufficient literature base to draw a reasonable conclusion but not such a large literature base that a traditional "evidence-based" review, meta-analysis, or systematic review can be performed.

Atrial fibrillation (AF) is a very common dysrhythmia presenting to Emergency Departments (EDs). ... more Atrial fibrillation (AF) is a very common dysrhythmia presenting to Emergency Departments (EDs). Controversy exists regarding the optimal clinical therapy for these patients, which typically focuses on rhythm rate-control and admission or cardioversion and discharge home. Is ED cardioversion of recent-onset atrial fibrillation safe, effective, and does it result in positive meaningful patient outcomes? Five observation studies with nearly 1600 ED patients with atrial fibrillation treated with either rate-control or cardioversion were reviewed and results compiled. Overall, ED cardioversion for recent-onset AF seems safe and effective, with success rates ranging from 85.5% to 97% in these studies. Although further research should seek to identify patients at low risk for thromboembolic complication, more rigorously assess patient satisfaction, and show cost savings, emergency physicians should feel comfortable using this approach in select patients. ED cardioversion for recent-onset AF seems safe and effective.

When clinicians apply typical risk stratification in these cases, they may be led away from a full evaluation for acute coronary syndrome (ACS). A diagnosis of MI in an otherwise healthy patient should prompt consideration of embolic sources, including Lambl's excrescences (LEs), and echocardiographic evaluation may be necessary to make a final diagnosis. We present a case of LEs in an otherwise healthy 43-year-old male presenting with chest pain and elevated cardiac enzymes, and also review the cases of this rare event found in the literature.
