Published in 2021 at "Cardiac electrophysiology clinics"

DOI: 10.1016/j.ccep.2021.07.002

Abstract: Wide QRS complexes during supraventricular rhythms can be caused by fixed bundle branch block, functional (intermittent) bundle branch block, preexcitation, or toxic/metabolic causes. Functional bundle branch block can be caused by long-short aberrancy (usually physiologic),… read more here.
