In brief: Increased vagal act

When the vagus nerve is stimulated, it is called vagal surge, the response is often a reduction in heart-rate or breathing.
In some cases, excessive stimulation can cause someone to have what is known as a vaso-vagal response, appearing to fall into a faint or coma because his or her heart rate and blood pressure drop so much.
