Preferred medications that slow atrioventricular (AV) node conduction include beta blockers (eg, atenolol, metoprolol, propranolol) and calcium channel blockers (eg, verapamil, diltiazem). These medications are used to control ventricular rates. They are also used in patients who are taking class IA or IC antiarrhythmic drugs (to prevent rapid ventricular response, which can occur when the atrial rate is slowed).
