Key result
Successful slow pathway ablation increases Wenckebach cycle length in typical AVNRT independent of dual physiology.
Why the study?
Does slow pathway ablation alter AV node conduction curves in patients with typical AVNRT?
Cohort (n=85)
Does slow pathway ablation alter AV node conduction curves in patients with typical AVNRT?
p-value: p=<0.05
Slow pathway ablation for AVNRT increases the Wenckebach cycle length regardless of whether dual AV node physiology is completely eliminated or persists.

Ablation may prolong AV nodal refractoriness beyond dual physiology elimination; leaves open impact on recurrence and requires prospective validation.
Geller et al. (2000) conducted a cohort in Typical AVNRT (n=85). Successful slow pathway (SP) ablation vs. Baseline (pre-ablation) values was evaluated on Changes in AV node Wenckebach cycle length (WB-CL) (p=<0.05). Successful slow pathway ablation significantly increased AV node Wenckebach cycle length in patients with typical AVNRT, independent of the persistence or elimination of dual physiology (P<0.05).
