Ventriculatrial block during atrioventricular nodal reentrant tachycardia suggesting existence of an upper common pathway.
Studies on the mechanisms of atrioventricular nodal reentrant tachycardia (AVNRT) have yet to clarify whether the slow and fast pathways connect directly with the atria or via an upper common pathway. Although a "final common pathway" connecting the slow and fast pathways to the proximal His bundle was thought to be part of the reentrant circuit, debate on the presence of an upper common pathway continues. We report a case of AVNRT continuing despite the occurrence of ventriculoatrial block, thus supporting the existence of an upper common pathway.
