The result is an increase in the heart rate. Conversely, stimulating the parasympathetic nervous system (vagal nerves to the heart) increases the resting potential and decreases the rate of diastolic depolarization; under these circumstances the heart rate slows. The...
Making the world better, one answer at a time. The vagus never innervates the heart and affects the SA node. Otto Loewi discovered that the vagus nerve through the action of Ach (a neurotransmitter) slowed the heart. So the vagus nerve can slow the action (or beating) of the heart. The vagus nerve releases the neurotransmitter, aceytlcholine, that slows down the heart rate. It is not the nerve impulses per se that do this, rather it is the the rele â¦ ase of transmitter and it's interaction with post-synaptic receptors that have this effect.
