Digoxin (A) acts on cardiac muscle by inhibiting the sodium-potassium pump. Propranolol (C) is a beta-blocker that acts on beta-adrenergic receptors. Procainamide (D) is a Class I antiarrhythmic agent that blocks sodium channels. Thus, Verapamil is the correct choice based on its mechanism of action on acetylcholine-sensitive K+ channels.
