Intraventricular Delay
Intraventricular delay is a term used for a wide QRS (QRS > 120 ms) and does not meet the criteria for LBBB or RBBB.

Intraventricular delay is not diagnosed if the rhythm has a ventricular origin, such as ventricular tachycardia, idioventricular rhythm, ventricular escape beats, or ventricularly paced beats.
