If blood pressure is too high or if the heart is beating too quickly, the carotid sinus detects the changes and sets in motion a reflex that slows the heart and lowers blood pressure. You could have pressed on the carotid sinus and triggered heart slowing or heart stoppage, along with a drop in blood pressure.
D’autre part, What is carotid sinus syndrome?
Carotid sinus syndrome (CSS) is a disease of the autonomic nervous system presenting with syncope, especially in older males who often have cardiovascular disease. The aetiology is unknown and epidemiological data is limited.
De plus, What happens if you press on your carotid artery?
You could have pressed on the carotid sinus and triggered heart slowing or heart stoppage, along with a drop in blood pressure. That brought you to your knees. Doctors sometimes massage the carotid sinus to put an end to a rapid heartbeat. Doing it unknowingly or when alone can be dangerous.
Ensuite, 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.
How is carotid sinus hypersensitivity treated?
Permanent pacing is discouraged in patients with a hypersensitive cardioinhibitory response to carotid sinus stimulation in the absence of symptoms. The consensus is that dual chamber pacing (DDD, DVI, DDI) is optimal in the patients. However, VVI mode is also effective in preventing recurrent syncope in some patients.

What is carotid sinus hypersensitivity?
Carotid sinus hypersensitivity (CSHCSHCarotid Sinus Hypersensitivity (CSH) is a condition that commonly manifests as syncope. There are hypersensitive receptors in the carotid sinus, which cause an exaggerated response when they are stimulated, leading to CSH.www.ncbi.nlm.nih.gov › books › NBK559059Carotid Sinus Hypersensitivity – StatPearls – NCBI Bookshelf) consists of the observation that stimulation of the carotid arterycarotid arteryThe carotid arteries are a pair of blood vessels located on both sides of your neck that deliver blood to your brain and head. Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries).www.mayoclinic.org › symptoms-causes › syc-20360519Carotid artery disease – Symptoms and causes – Mayo Clinic baroreceptorsbaroreceptorsBaroreceptors (or archaically, pressoreceptors) are sensors located in the carotid sinus (at the bifurcation of external and internal carotids) and in the aortic arch. They sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained.en.wikipedia.org › wiki › BaroreceptorBaroreceptor – Wikipedia results in a greater than expected fall in heart rate and drop in blood pressure.
What complications are associated with carotid sinus massage?
Eight had transient neurological complications possibly attributable to carotid sinus massage: visual disturbance, ‘pins and needles’ and sensation of finger numbness in two cases each, leg weakness in one and sensation of ‘being drunk’ in one.

What does carotid sinus massage do?

What is the carotid sinus?
The carotid sinus is a dilation at the base of the internal carotid artery. The nearby carotid body is a fibrous-covered structure that rests posteriorly to the carotid bifurcation. The blood supply to carotid sinus is by the vasa vasorum vessels.
What does the carotid sinus do?
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 are the symptoms of a blocked artery in the neck?
– Sudden numbness or weakness in the face or limbs, often on only one side of the body.
– Sudden trouble speaking and understanding.
– Sudden trouble seeing in one or both eyes.
– Sudden dizziness or loss of balance.
– Sudden, severe headache with no known cause.
Why is it important not to massage the carotid artery?
One caution about massage. The carotid arteries, which run along either side of the neck, have nerve endings that respond to changes in blood pressure. Massaging these sensors can decrease the heart rate, sometimes enough to cause fainting.
