Failure of right atrial premature beats to reset atriofascicular tachycardia.
A patient with a right atriofascicular (Mahaim) tachycardia was found to have inducible antidromic supraventricular tachycardia, but atrial premature beats from the right atrial free wall failed to reset the tachycardia. An interesting transition from AV nodal reentry tachycardia to Mahaim tachycardia is also presented.
