Use of medication is not indicated for treatment of asymptomatic first-degree atrioventricular (AV) block. However, in patients with severe bradycardia or those with the possibility of progression to higher-degree AV block, medications (eg, atropine, isoproterenol) can be used in anticipation of insertion of a cardiac pacemaker.
