Treatment for a Mobitz type I<unk> -degree AV block (Wenckebach) is often not necessary. Occasionally Mobitz type 1<unk>  degree AV blocks may result in bradycardia leading to hypotension and responds well to medications. If unresponsive to atropine or beta-adrenergic agonists, pacing (transcutaneous or transvenous) should be initiated for stabilization. If the patient is on any beta-blockers, calcium channel blockers or digoxin, the medications should be discontinued. All patients with Mobitz 1 block should be admitted and monitored. Treatment for a Mobitz type II involves initiating pacing as soon as this rhythm is identified. Mobitz type II<unk> -degree AV blocks may imply structural damage to the AV conduction system. This rhythm often deteriorates into a complete heart block. These patients require transvenous pacing until a permanent pacemaker is placed. Unlike Mobitz type I<unk>  degree AV block (Wenckebach), Mobitz type II AV block often do not respond to atropine or beta-adrenergic agonists.
