Is the carotid sinus palpable?

The carotid pulse is characterized by a smooth, relatively rapid upstroke and a smooth, more gradual downstroke, interrupted only briefly at the pulse peak. These palpable pulsatile changes in the carotid arterial diameter are virtually identical to the intraluminal pressure pulse .

How do I find my carotid sinus?

The carotid sinus is located at the upper border of the thyroid cartilage, medial to the sternocleidomastoid muscle (Figure 1). Hold your index and middle fingers together and slide them from the thyroid cartilage posteriorly, toward the patient’s spine, until you feel the carotid pulse.

Is it normal to feel your carotid artery?

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 .

What happens when carotid sinus is pressed?

Carotid sinus hypersensitivity is an exaggerated response to pressure applied to the carotid sinus located in the carotid bifurcation, resulting in bradycardia, vasodilation, and hypotension . This response is manifested clinically as syncope or presyncope and can cause fatal consequences.

Is it normal to feel your pulse in your neck?

How do you check a carotid sinus reflex?

Carotid sinus reflex sensitivity is assessed by measuring heart rate and blood pressure responses to carotid sinus massage (Figure 46-4). Cardioinhibition and vasodepression are more common on the right side.

Where do you feel the pulsation of the common carotid artery?

Can massaging your neck cause a stroke?

Neck massage should not be performed by patients. Neck massage/manipulation continues to be a cause of stroke to consider . Ischemic stroke after CS and carotid body manipulation is due to thromboembolism by rupture of a plaque or by hypoperfusion due to repetitive hypotension.

When should you not do carotid massage?

A history of ventricular fibrillation or tachycardia, or a previous adverse reaction to carotid sinus massage are also absolute contraindications.

Why does my neck hurt where my carotid artery is?

One of the common causes of pain in the neck is soreness and tenderness of one or both carotid arteries and is related to overdistention, relaxation, and increased pulsation in this vessel . The syndrome of vascular neck pain is closely related to the various forms of extracranial vascular headache.

Why is my pulse beating hard in my neck?

Feeling palpitations in the head or neck is sometimes a sign of a particular type of tachycardia called “ AV nodal reentry tachycardia .” This is a rapid heart rhythm caused by an electrical short circuit in the heart.
