About this study

The AFFELECT -study compares two types of treatment modalities for acute atrial fibrillation or flutter for patients in whom rhythm control is desirable. The main purpose is to observe if these arrhythmias can be safely treated electively (within 5-9 days). All patients are recruited in the emergency department. Patients must be in good clinical condition so that they can be discharged regardless to which treatment modality is randomly selected to them. Patients randomized to conventional care are treated conventionally which means acute rhythm control is applied by electrical or medical cardioversion in the emergency department (within 48 hours of onset of the arrhythmia). Patients randomized to elective care are discharged immediately after adequate temporary rhythm control is assured. All patients will visit a cardiologist out-patient clinic at approximately one week after the emergency room visit. Patients randomized to elective treatment and still in atrial fibrillation or in atrial flutter will be restored to sinus rhythm by electrical or medical cardioversion at the out-patient clinic. Cardiovascular status and treatment options are evaluated for all patients. Anticoagulation is managed according existing guidelines for all patients. Due to possibility of delayed cardioversion in the interventional group (elective care group), all patients receive anticoagulation before the out-patient clinic despite their thromboembolic risk. All patients who have not received adeq…
