The vagal nerve stimulator has two parts: an electrode that wraps around the left vagus nerve in the neck; and a pulse generator, which is implanted under the skin below the collarbone. The two parts are connected by a wire.

What is vagal nerve stimulation?
Vagal nerve stimulation is a treatment for epilepsy in which an electrode is implanted in the neck to deliver electrical impulses to the vagus nerve.
What is the purpose of vagal nerve stimulation?
Vagal nerve stimulation is an alternative to medication or surgical removal of brain tissue in controlling epileptic seizures.
What success rate does vagal nerve stimulation have?
Approximately half of all patients who have received vagal nerve stimulation experience about a 50% reduction in seizures. Another 9% of patients obtain complete relief from seizures.
How is excessive vagal stimulation be reflected in a routine physical examination when caused by severe depression?
Excessive vagal stimulation can be caused by sever depression. The impact on this nerve cannot be detected in a routine physical examination. This must be diagnosed through use of an MRI.
What is the golden bough in the underworld?
The Vagus nerve. Vagal stimulation brings you into a perinatal matrix. Read books by Stan Grof.
Increased vagal stimulation would cause?
"Increased vagal stimulation would cause..." The heart rate to decrease.
How can the heart overcome excessive vagal stimulation?
The heart can overcome excessive vagal stimulation through sympathetic reflexes and the initiation of a rhythm by the Purkinje fibers.
What happens to the heart rate with vagal stimulation?
Your heart is able to independently contract without nerve stimulation. However, frequency of these contractions if the heart was not innervated at all would roughly be 100 beats per minute. A resting individual does not need his or her heart to beat that fast to adequately supply blood to the rest of the body. So when at rest the vagus nerve (the branch innervating the heart) kicks in and slows these contractions down so as not to waste energy.
What causes vagal escape?
when cardiac muscle begins to contract after a brief period of rest after vagal stimulation its initial strength of contraction increases to a plateau by staircase effect strong vagal stimulation of heart can stop heart beat for few seconds
What nerve conveys parasympathetic signals to the heart?
Vagal
Does the vagus nerve stimulator cause vagal inhibition?
Yes
What is transcutaneous electrical nerve stimulation also called?
Electrical nerve stimulation
