The vagus nerve is responsible for slowing down the heart rate by releasing acetylcholine, which decreases the electrical conductivity of the heart and decreases the firing rate of the sinoatrial node. Stimulation of the cardiac accelerator nerve would increase heart rate, while stimulation of the hypoglossal, spinal accessory, and phrenic nerves have no direct effect on heart rate.
