Atrioventricular nodal reentry tachycardia (AVNRT), identified as the most prevalent form of regular tachycardia in humans,3 exhibits a strong relationship with the anatomy and physiology of the AV node (AVN) and junction. Despite the temporal distance, Koch's triangle and pyramid remain a repository of unresolved mysteries.
