CAROTID SINUS MASSAGE Meaning and
Definition
-
Carotid sinus massage refers to a medical technique that involves applying gentle pressure or massaging the carotid sinus, a small, oval-shaped area located on each side of the neck where the common carotid artery divides into internal and external branches. This massage technique is typically conducted by a healthcare professional and is used to diagnose and treat certain medical conditions.
During a carotid sinus massage, the healthcare provider applies gentle pressure to the carotid sinus area with their fingertips. The pressure stimulates the baroreceptors, which are specialized sensory nerve endings responsible for detecting changes in blood pressure. These baroreceptors send signals to the brain, which in turn regulates heart rate and blood pressure.
Carotid sinus massage can be used as a diagnostic tool for identifying conditions such as carotid sinus hypersensitivity or carotid sinus syncope. It can also be effective in treating certain forms of supraventricular tachycardia (SVT) or rapid heart rhythms through the activation of the baroreceptor reflex and subsequent slowing of the heart rate.
However, due to the potential risks associated with carotid sinus massage, including the possibility of causing stroke or damage to the carotid artery, it should only be performed by trained medical professionals in a controlled environment. Additionally, certain individuals, such as those with carotid artery disease or a history of stroke, may be at higher risk and should avoid this procedure.
