Best answer: What is one of the primary goals of carotid sinus massage?

Massage. Massage of the carotid sinus, carotid sinus massage is used to diagnose carotid sinus syncope and is sometimes useful for differentiating supraventricular tachycardia (SVT) from ventricular tachycardia. Like the valsalva maneuver, it is a treatment for acute SVT.

What is the purpose of carotid sinus massage?

Overview. Carotid sinus massage is a major diagnostic test for carotid sinus hypersensitivity, which may be manifested as dizziness or syncope. Carotid sinus massage is also used in emergency settings to diagnose or treat paroxysmal supraventricular tachycardia.

What is carotid artery massage?

Carotid sinus massage is a simple bedside maneuver that helps to clarify the type and sometimes also the mechanism of different rhythm disturbances. The major indication for carotid sinus massage is the diagnosis of tachyarrhythmias in which the atrial activity is either absent or intermittently present.

What is carotid sinus stimulation?

Stimulation of the carotid sinus baroreceptor (via stretching) stimulates the glossopharyngeal nerve, which in turn stimulates the vasomotor center in the medulla via the tractus solitarius, which then modulates the activity of the autonomic nervous system (suppresses sympathetic and stimulates parasympathetic output).

How does the carotid sinus reflex work?

The mechanics behind this are simple: If the Carotid Sinus senses high blood pressure, it stimulates the corresponding brain canter to slow the heart down, at least until the blood pressure comes down.

What happens if you massage your 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.

Is carotid massage safe?

Carotid sinus massage is safe if done carefully. CSM is contraindicated in patients with a history of cerebrovascular disease or carotid bruits, because it can cause cerebrovascular accident (CVA, stroke).

How do you massage a carotid artery gently?

Carotid Massage: This technique is performed with the patient’s neck in an extended position, the head turned away from the side being massaged. Only one side should be massaged at a time. Pressure is applied underneath the angle of the jaw in a gentle circular motion for about 10 seconds.

What is often caused by carotid massage?

Carotid 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.

What happens when carotid sinus is pressed?

by mechanical stimulation of the receptors in its wall, produces reflexly bradycardia and peripheral vasodilatation. On the other hand, pressure applied below the carotid sinus, by occluding the carotid artery, causes hypotension in the sinus, and produces reflexly tachycardia and peri- pheral vasoconstriction.

What side of neck is carotid artery?

The carotid arteries are two large blood vessels that supply oxygenated blood to the large, front part of the brain. This is where thinking, speech, personality, and sensory and motor functions reside. You can feel your pulse in the carotid arteries on each side of your neck, right below the angle of the jaw line.

Can you feel the carotid sinus?

You can feel your carotid artery simply by placing a finger on your neck.

What happens when baroreceptors in your carotid arteries detect elevated blood pressure?

Carotid sinus baroreceptors are free-nerve-ending mechanoreceptors that stretch in response to increased arterial blood pressure. Activation of baroreceptors results in increased firing of action potentials with the rapidity proportional to the degree of mechanical stretch.

Where are the carotid baroreceptors located?

Baroreceptors are mechanoreceptors located in the carotid sinus and in the aortic arch. Their function is to sense pressure changes by responding to change in the tension of the arterial wall. The baroreflex mechanism is a fast response to changes in blood pressure.

Where are the carotid bodies?

The carotid body (carotid glomus or glomus caroticum) is a small cluster of chemoreceptors and supporting cells located near the bifurcation of the carotid artery. The carotid body detects changes in the composition of arterial blood flowing through it, mainly the partial pressure of oxygen, but also of carbon dioxide.
