In brief: A Drop in Heart Rate

Vasovagal syncope refers to passing out when the vagus or 10th cranial nerve is stimulated.
One important function of the vagus is to slow your heart down. Any activity that increases the pressure inside your abdomen can stimulate the vagus. So vasovagal syncope often happens when one is bearing down to try to urinate as in elderly men standing at the toliet.
