May support intrinsic remodeling after slow pathway ablation in pediatric AVNRT; leaves open effects on recurrence or ablation strategy.
Does slow pathway ablation reduce the fast pathway effective refractory period in pediatric patients with AVNRT?
Slow pathway ablation in pediatric patients with AVNRT results in a substantial shortening of the fast pathway effective refractory period, which is not fully explained by changes in autonomic tone.
