Antiarrhythmic medicines help return the heart to its normal sinus rhythm, maintain the rhythm after it has been achieved, and/or reduce the heart rate while you are in atrial fibrillation. These medicines stabilize the heart muscle tissue. Antiarrhythmics such as amiodarone or sotalol also slow the heart rate by blocking.
Antiarrhythmic medicines are used to convert atrial fibrillation to a normal rhythm. These medicines may be used before electrical cardioversion and may help maintain a normal heart rhythm after successful cardioversion. Ibutilide, another antiarrhythmic, may improve chances of successful cardioversion when used before cardioversion.
