Vagus Nerve Function. Vagus nerve oversees the internal organ functions such as sustain the peristaltic movements of the gastrointestinal tract, heart rate, respiratory rate and vasomotor activity. That means it's a pretty major nerve in the human body. This 10th cranial nerve is found in pairs in the human body. But, it also holds some sympathetic nature through the peripheral chemoreceptors. Some people are particularly prone to the vasovagal reflex, and their blood pressure and heart rate changes can cause loss of consciousness — a condition called "vasovagal syncope.". Stimulation of the vagus nerve is a medical procedure that is used to try to treat a variety of conditions. The sympathetic side increases alertness, energy, blood pressure, heart rate, and breathing rate. The vagus nerve has two functions. Vagal stimulation can be achieved quite easily by employing the Valsalva maneuver. It can be done either manually or through electrical pulses. Stimulation of the vagus nerve could aid the management of cardiovascular diseases, atrial fibrillation being one of them.
