Overview
Infra-Hisian blocks are defined as impaired conduction in the electrical system of the heart that occur below the AV node.
Infrahisian block describes block of the distal conduction system. Types of infrahisian block include:
- Type 2 second degree heart block (Mobitz II)[dubious ]
- Left bundle branch block
- Right bundle branch block
Of these types of infrahisian block, Mobitz II heart block is considered most important because of the possible progression to complete heart block.
