MSH: An adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.,NCI: An ethanolamine derivative with Class III antiarrhythmic and antihypertensive properties. Sotalol is a nonselective beta-adrenergic receptor and potassium channel antagonist. In the heart, this agent inhibits chronotropic and inotropic effects thereby slowing the heart rate and decreasing myocardial contractility. This agent also reduces sinus rate, slows conduction in the atria and in the atrioventricular (AV) node and increases the functional refractory period of the AV node.
