How Does the Medication Work?

Sotalol belongs to two different classes of drugs; it is both a beta blocker and a Class III antiarrhythmic medication.
 
As a beta blocker, sotalol slows down the heart rate and increases the amount of time that a certain area of the heart (the AV node) is not responsive to an electrical signal. This means that if an electrical signal comes too soon, which could happen with atrial fibrillation or atrial flutter, the signal will not pass on to the rest of the heart.
 
As a Class III antiarrhythmic medication, sotalol blocks potassium channels in the heart. This action helps to control an irregular heart rhythm.
