Overview
Intraventricular conduction delay is characterized by a prolonged time for electrical impulses to traverse the ventricles of the heart as demonstrated by a wide QRS interval or QRS prolongation.
Causes
- Incomplete left bundle branch block
- Incomplete right bundle branch block
- Left anterior fascicular block
- Left bundle branch block
- Left posterior fascicular block
- Non-specific intraventricular conduction delay (NSIVCD) (when the QRS is wide and the definitions of LBBB and RBBB are not met)
- Right bundle branch block
