Another form of this medicine, called Sotalol AF, is used to treat heart rhythm disorders of the atrium (the upper chambers of the heart that allow blood to flow into the heart). Sotalol AF is used in people with atrial fibrillation or atrial flutter. Sotalol (Betapace and Sorine) is not used for the same conditions that sotalol AF (Betapace AF) is used for.
