What are the risks of cardioversion for atrial fibrillation or atrial flutter?
The risks of cardioversion for atrial fibrillation or atrial flutter include the risk of stroke, which can be prevented with anticoagulation therapy. Other risks include arrhythmias or tachycardias, cardiac perforation, and death. Additionally, prophylactic anticoagulation should be used to reduce the risk of thromboembolic events in patients undergoing electrical cardioversion for atrial fibrillation or atrial flutter.
