The vagus nerve (CN X) is responsible for parasympathetic innervation to the heart, which can lead to a decrease in heart rate. It also plays a role in the gag reflex and sensations from the throat and the abdominal organs, which can explain the nausea. The symptoms described are consistent with stimulation of the vagus nerve.
