Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm. When rate control is not successful enough or when it is not able to improve the symptoms of patients rhythm control (either pharmacological or electrical) should be considered. Electrical cardioversion involves the restoration of normal heart rhythm through the application of a defibrillator. The pharmalogical method is performed with usage of medications, such as amiodarone, dronedarone, procainamide, ibutilide, propafenone or flecainide. Whichever method of cardioversion is used, approximately 50% of patients relapse within one year, although the continued daily use of oral antiarrhythmic drugs may extend this period.
