Atypical Fast-Slow Atrioventricular Nodal Reentrant Tachycardia Incorporating a 'Superior' Slow Pathway A Distinct Supraventricular Tachyarrhythmia

摘要

Background The existence of an atypical fast-slow (F/S) atrioventricular nodal reentrant tachycardia (AVNRT) including a superior (sup) pathway with slow conductive properties and an atrial exit near the His bundle has not been confirmed.
