AVNRT elimination by slow pathway ablation often spares conduction properties; leaves open whether it disrupts pathway linkage rather than directly impairing the slow pathway.
Does "slow pathway potential" guided catheter ablation alter AV nodal physiology in patients with AV nodal reentrant tachycardia?
Elimination of AV nodal reentrant tachycardia by slow pathway ablation may occur through disruption of the link between fast and slow pathways rather than direct impairment of the slow pathway itself in a significant proportion of patients.
Takahashi et al. (1994) studied this question.
