Wo ist der Carotis Sinus Nerv?

Among those who are symptomatic, the following symptoms and signs could be observed in clinical settings:
- Recurrent dizziness, near-syncope.
- Recurrent syncope.
- Nonaccidental, unexplained falls.
- Symptoms produced by head turning or wearing garments with tight-fitting collars.
How is carotid sinus syndrome treated?
In this setting, cardiac pacing is probably the procedure of choice. In those patients, however, who have syncope or near-syncope associated with a hypersensitive carotid sinus and who have no evidence of a cardiac conduction defect, the treatment of choice is probably carotid sinus denervation.
What does carotid neck pain feel like?
Carotidynia is a pain that you feel in your neck or face. It is linked with physical changes that can happen in a carotid artery in your neck. Your neck may feel tender in the area of the artery. The pain often goes up the neck to the jaw, ear, or forehead.

Which side of the neck is the carotid artery?

How can the carotid sinus cause sudden death?
Carotid sinus reflex death is a potential etiology of sudden death in which manual stimulation of the carotid sinus allegedly causes strong glossopharyngeal nerve (Vagus nerve is for aortic arch baroreceptors) impulses leading to terminal cardiac arrest.
What does carotid sinus detect?
The carotid sinus baroreceptor, innervated by the glossopharyngeal nerve (cranial nerve IX), is located in the adventitia of the carotid artery and is activated by stretching of the blood vessel wall. The physiological role of this mechanoreceptor is to detect, respond, and regulate the systemic blood pressure.
What is the main cause of carotid artery stenosis?
Atherosclerosis causes most carotid artery stenosis. In this condition, fatty deposits build up along the inner layer of the arteries forming plaque. The thickening narrows the arteries and decreases blood flow or completely blocks the flow of blood to the brain.
