Abstract

Differential diagnoses of regularly irregular narrow QRS tachycardias are AV re-entrant tachycardia (AVRT) with alternating antegrade AVN pathways, atypical AV nodal re-entrant tachycardia (AVNRT) with alternating antegrade AVN pathways, and atrial tachycardia (AT) with alternating antegrade AVN pathways or with Wenckebach periodicity.
