DC cardioversion of atrial fibrillation and atrial flutter in the emergency department: improving specialist protocols for the generalist.

Background: Direct current cardioversion (DCCV) is a safe and effective treatment for recent-onset atrial fibrillation (AF) or flutter and when performed in the emergency department (ED), it can provide an excellent treatment option for patients as well as reducing unnecessary hospital admissions and healthcare costs. However, appropriate periprocedural anticoagulation is absolutely essential to reduce the risk of adverse outcomes, chiefly thromboembolic stroke. Our intention was for 100% of patients undergoing DCCV in the ED to receive appropriate periprocedural anticoagulation.
