Key result
The AH interval during slow pathway conduction correlated significantly with the distance between the successful ablation site and the His-bundle (P < 0.001).
Observational (n=35)
p-value: p=<0.001
There is a significant correlation between the AH interval during slow pathway conduction and the distance of the successful ablation site from the His bundle, suggesting anatomic factors influence slow pathway conduction.

May inform ablation site selection to avoid His bundle; leaves open prospective confirmation of clinical utility.
Geller et al. (2004) conducted an observational in AV nodal reentrant tachycardia (AVNRT) (n=35). Slow pathway ablation was evaluated on Correlation between the AH interval during slow pathway conduction and the distance between the successful ablation site and the His-bundle (p=<0.001). The AH interval during slow pathway conduction correlated significantly with the distance between the successful ablation site and the His-bundle (P < 0.001).
