• Carotid sinus hypersensitivity (CSH) is an exaggerated response to carotid sinus baroreceptor stimulation. (medscape.com)
  • The carotid sinus reflex plays a central role in blood pressure homeostasis. (medscape.com)
  • Changes in stretch and transmural pressure are detected by baroreceptors in the heart, carotid sinus, aortic arch, and other large vessels. (medscape.com)
  • Afferent impulses are transmitted by the carotid sinus, glossopharyngeal, and vagus nerves to the nuclei tractus solitarius and the para median nucleus in the brain stem. (medscape.com)
  • In CSH, mechanical deformation of the carotid sinus (located at the bifurcation of the common carotid artery) leads to an exaggerated response with bradycardia or vasodilatation, resulting in hypotension, presyncope, or syncope. (medscape.com)
  • The hemodynamic changes following carotid sinus stimulation are independent of body position. (medscape.com)
  • The term spontaneous carotid sinus syndrome refers to a clinical situation in which the symptoms can be clearly attributed to a history of accidental mechanical manipulation of the carotid sinuses (eg, taking pulses in the neck, shaving) and CSH is reproduced by carotid sinus massage. (medscape.com)
  • Spontaneous carotid sinus syndrome is rare and accounts for about 1% of causes of syncope. (medscape.com)
  • 2) High pressure receptors (baroreceptors) - these are found in the carotid sinus and the aortic arch. (endocrinesurgeon.co.uk)
  • Arterial (High-Pressure) Baroreceptors: Aorta and carotid sinus participate in the maintenance of ECF volume. (abcmedicalnotes.com)
  • The provisional OH may occur en presence of hypovolemia, or as a side effect from medication affecting the SNS functions, In these cases arterial pressure is recovered by correcting the triggering factor. (journalofneuropsychiatry.cl)
  • Some people with mild aortic stenosis may not require any treatment, while others may need medications to manage symptoms or prevent complications. (prime-cardiology.com)
  • Aortic stenosis is a heart condition that occurs when the aortic valve narrows and restricts blood flow from the heart to the rest of the body. (prime-cardiology.com)
  • In some cases, aortic stenosis may be caused by rheumatic fever, a complication of strep throat that can damage heart valves. (prime-cardiology.com)
  • In conclusion, aortic stenosis is a heart condition that can cause a range of symptoms and complications. (prime-cardiology.com)
  • Low-Pressure Baroreceptors: Found in Thorax, on the venous side of the circulation. (abcmedicalnotes.com)
  • Although baroreceptor function usually diminishes with age, some people experience hypersensitive carotid baroreflexes. (medscape.com)
  • With proper diagnosis and treatment, many people with aortic stenosis are able to manage their symptoms and maintain a good quality of life. (prime-cardiology.com)
  • Sensing the level of O2 and CO2 is an essential factor for the brain to know how fast the lungs need to fill and empty to keep the O2 levels high enough and the CO2 levels low enough to keep all of the cells of the body healthy. (khanacademy.org)
  • The interchange by diffusion along concentration gradients of oxygen and carbon dioxide between the cells of the body and the interstitial fluid surrounding them, which in one sense is a process of nutrition. (easynotecards.com)
  • If you or a loved one is experiencing symptoms of aortic stenosis, it is important to speak with a healthcare provider to determine the best course of treatment. (prime-cardiology.com)
  • Higher centres of the brain can also exert an effect on vasopressin release so that massive release of vasopressin can occur in times of emotion and physical stress to the body. (endocrinesurgeon.co.uk)
  • Aortic stenosis is typically diagnosed through a combination of physical exams, medical history review, and diagnostic testing. (prime-cardiology.com)
  • MATERIALS AND METHODS: Superficial and deep dissections were performed on the anterior triangle of the neck to expose the carotid region in twenty-one formalin-fixed donor cadavers. (bvsalud.org)
