If conduction occurs via the slow pathway, how does the conduction time compare to the fast pathway?

Explanation:
Conduction time through an AV nodal pathway depends on how fast the pathway conducts and how long the path is. The slow pathway has a slower conduction velocity and a longer route from the atrium to the His bundle, so the impulse takes more time to traverse it. That means conduction via the slow pathway is longer than conduction via the fast pathway. The fast pathway conducts more quickly, giving a shorter conduction time. This difference is why the slow pathway often produces a longer AH interval when that route is used.
