Electrical cardioversion is an outpatient procedure. With this procedure, a cardiologist gives a mild shock to the heart to convert the chaotic rhythm back to normal. After undergoing electrical cardioversion to treat atrial fibrillation, your doctor may prescribe an anti-arrhythmic drug to keep your heart rate in a regular rhythm. Some commonly used anti-arrhythmic drugs include amiodarone (Cordarone, Pacerone), propafenone (Rythmol), sotalol (Betapace), and dofetilide (Tikosyn). These drugs offer a great benefit to individuals with atrial fibrillation as they help keep the heart's rhythm normal. Still, there are side effects with anti-arrhythmic drugs such as fatigue, nausea, and dizziness. Sometimes ventricular arrhythmias, a life-threatening problem, can occur with these drugs, so your doctor will monitor you closely once you begin this regimen.
