Key result
Slow pathway radiofrequency ablation successfully eliminated atypical AVNRT presenting as wide QRS tachycardia with retrograde Wenckebach block, with no recurrence at 6 months.

Supports EP evaluation in ambiguous wide-complex tachycardia; leaves open generalizability beyond this single case.
Case Report (n=1)
This case highlights that AVNRT with retrograde Wenckebach block and baseline right bundle-branch block can mimic ventricular tachycardia, underscoring the diagnostic value of intracardiac electrophysiological evaluation.
Mo et al. (2026) conducted a case report in Atrioventricular nodal reentrant tachycardia (AVNRT) (n=1). Slow pathway radiofrequency ablation was evaluated on Tachycardia recurrence. Slow pathway radiofrequency ablation successfully eliminated atypical AVNRT presenting as wide QRS tachycardia with retrograde Wenckebach block, with no recurrence at 6 months.
