Key result
A case report of atrioventricular nodal reentrant tachycardia continuing despite ventriculoatrial block supports the existence of an upper common pathway.
Case Report (n=1)
This case report provides electrophysiological evidence supporting the existence of an upper common pathway in the AVNRT reentrant circuit.
Hypothesis-generating for upper common pathway in AVNRT; does not support practice changes without further validation.
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.

Köse et al. (2005) conducted a case report in Atrioventricular nodal reentrant tachycardia (AVNRT) (n=1). A case report of atrioventricular nodal reentrant tachycardia continuing despite ventriculoatrial block supports the existence of an upper common pathway.
