Tedisamil (37-dicyclopropylmethyl-99-tetramethylene-37-diazabicyclo-331-nonane) is an experimental class III antiarrhythmic agent currently being investigated for the treatment of atrial fibrillation. Tedisamil blocks multiple types of potassium channels in the heart resulting in slowed heart rate. While the effects of tedisamil have been demonstrated in both atrial and ventricular muscle repolarization is prolonged more efficiently in the atria.
