A class III antiarrhythmic drug used to convert atrial fibrillation and flutter to normal sinus rhythm and to maintain normal rhythm after conversion. It works by blocking potassium channels in the heart, prolonging the action potential. It can cause a potentially dangerous prolongation of the QT interval leading to life-threatening arrhythmias, so initiation must occur in hospital with continuous cardiac monitoring.
