Overview
Intraventricular conduction delay can be caused by structural abnormalities in the bundle of His or purkinje system or ventricular myocardium, functional refractoriness in a portion of the conduction system (i.e., aberrant ventricular conduction), or ventricular preexcitation over a bypass tract. Intraventricular conduction disturbances can be broadly classified based upon the underlying pathophysiology or based upon the site of block (anatomical classification). However, the anatomic description of conduction abnormalities are not intended to localize sites of impaired function precisely because the electrocardiographic changes may be caused by abnormalities in various sites within the ventricles.
