What is the treatment for atrioventricular block?

Permanent pacing is the therapy of choice in patients with symptomatic atrioventricular (AV) block with bradycardia. Temporary transcutaneous or transvenous pacing is required if a slow heart rate (or asystole) caused by AV block requires correction and permanent pacing is not immediately indicated or not available.

What is the main cause of atrioventricular blocks?

The most common causes of AV block include: Fibrosis or sclerosis. Extra tissue can thicken, scar, and damage the pathways that send signals from the upper part to the lower part of your heart. Coronary artery disease.
