In contrast, conduction back to the atria via a slow nodal pathway might well leave a path of refractorness in the A-V node and transitional tissue that would prevent return of the impulse to the ventricles.
The refractory period of A-V bypass tracts often is long, which is the basis of the initiation of orthodromic A-V reciprocating tachycardia when an atrial premature complex blocks in the bypass tract and is conducted down the A-V node.
Like the one shown here, none of them interrupted the tachycardia because none of them depolarized the A-V node.
