Supraventricular tachycardia with left aberrant conduction due to retrograde invasion into the left bundle branch
A description is given of a patient with an atrioventricular nodal tachycardia with left aberrant conduction changing into nonaberrant conduction after a ventricular premature beat. Functional left bundle-branch block by retrograde invasion into the left bundle branch is thought to be responsible for this phenomenon.
