An atrioventricular block (or AV block) is a type of heart block involving impairment of the conduction between the atria and ventricles of the heart.^[1] It usually involves the atrioventricular node, but it can involve other structures.

There are three types:

• First degree AV block
• Second degree AV block
• Third degree AV block
