Ashman aberrancy

An Ashman beat is a wide QRS complex with RBBB morphology during a supraventricular rhythm. The beat originates above the AV node but is not conducted normally through the ventricle. It classically occurs when there is a long RR interval followed by a short RR interval (i.e. in atrial fibrillation) where the right bundle branch is still refractory from the beat before.
