Overview
Treatment goal is to remove the extrinsic causes and treat reversible intrinsic causes. Drugs used in the treatment of AV nodal blocks include atropine, isoproterenol, theophylline, antibiotics treatment for lyme disease and treatment of ischemia. A permanent pacemaker is indicated for symptomatic bradycardia due to advanced second- or third-degree heart blocks.
Medical Therapy
- Permanent pacemaker is the treatment of choice for atrioventricular blocks and does not require concomitant pharmacologic treatment.
- Drugs that block AV nodal conduction must be discontinued.
Emergency Management
- Atropine may be administered in emergency management of atrioventricular block to improve AV conduction until a temporary transcutaneous or transvenous pacemaker is inserted. However, atropine can potentially worsen the conduction if the block is in the bundle of His.
