What would happen if the Na/K pump worked at half its current rate?

The purpose is to look at the function of the Na/K pump. Nothing would happen initially, since the Na+ and K+ movements in depolarization and repolarization are so slight that many action potentials can occur across the neuron before the ion imbalance needs to be restored. If many action potentials were passing along the neuron per unit time, slowing the NA/K pump would have the effect of not allowing all of the action potentials to pass until the resting potential was restored.
