WebAberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat. WebPedro Brugada, MD, PhD, is head of the cardiac arrhythmia unit at Hospital Estepona and the Heart Rhythm Management Centre at Brussels University Hospital in Brussels, Belgium.

The term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular atrial, and regular atrioventricular tachycardias. It is often used synonymously with AV nodal re-entry tachycardia (AVNRT), a form of SVT. thepinch.com

"WebSince aberrancy is almost always in the form of a bundle branch block morphology, V1 is the best lead for differentiating RBBB from LBBB; RBBB creates a positive deflection, and LBBB, a negative deflection. Therefore, the first order of business is to identify the direction of QRS forces in V1. " - Litfl aberrancy
