Nerve impulse is roughly na+ in k+ out to create an action potential. I wonder what having a plethora of na+ does to electric impulses within the nervous system.

Jangle, higher levels of sodium in the extra cellular fluid would change the electrochemical gradient across the cell membrane and could affect membrane potential. Perhaps the increase of flow through the sodium channels is changing the sensitivity of the vagus nerve via electrochemical force. Or actually having extra sodium in ecf would actually reduce the the electrical capacity of the cell and seems like it would definitely affect the voltage gated channels.
