Atrioventricular Nodal Reentry with Retrograde Lower Common Pathway Block: A Case Report
Key result
Retrograde ventriculoatrial block during AV nodal reentrant tachycardia with antegrade decremental lower common pathway conduction was observed in 1 female patient, mimicking atrial tachycardia.

Implication
May prevent misdiagnosis of AVNRT as atrial tachycardia; hypothesis-generating and leaves open broader prevalence.

Outcome
Demonstration of retrograde ventriculoatrial block and antegrade decremental lower common pathway conduction
Retrograde lower common pathway block during AVNRT can produce variable HA intervals despite constant atrial cycle length, which may lead to misdiagnosis as atrial tachycardia if not recognized.
