Overview
Ischemia of the conduction system results in conduction abnormalities in the heart. Atrioventricular blocks are common in inferior infarcts and intraventricular blocks are common in anterior wall infarcts.
Classification
Conduction abnormalities post-infarction can be classified as atrioventricular blocks and intraventricular blocks.
- Atriventricular blocks:
- Second degree blocks (Mobitz type I and II)
- Third degree
- Intraventricular block:
- Bundle branch blocks
- Bifascicular blocks
These blocks can be temporary or persistent.
