What is carotid sinus massage ? This is a procedure that is used to investigate unexplained dizziness, falls or faints. It involves gently massaging the carotid artery for 5 seconds on one side of your neck whilst monitoring your heart rhythm and blood pressure.
What does a carotid massage do?
Carotid sinus massage (CSM) is performed to terminate some supraventricular tachycardias (SVTs), such as AV node reentry and AV reentry SVTs. It may also be useful for sinoatrial (SA) reentrant SVT. CSM can be helpful to diagnose the atrial rhythm during a tachycardia by producing AV block.
What is often caused by carotid massage?
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.
What nerve does carotid massage stimulate?
The carotid sinus reflex occurs with changes in transmural pressure of the baroreceptors at the carotid sinus. Afferent signals are sent via glossopharyngeal and vagus nerves to the nucleus tractus solitarius. Efferent signaling occurs through sympathetic and vagus nerves to the heart and blood vessels.
What happens when you press carotid artery?
If you press gently on either side of your windpipe, in your neck, you may feel pulsations from the carotid arteries. Like any artery in the body, the carotid arteries may become diseased and blocked inside, either partly or completely.
Can carotid massage cause 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.
What happens if you press too hard on the carotid artery?
Do not press on the carotid artery on both sides of your neck at the same time. This may cause you to feel lightheaded or dizzy, or possibly faint. Apply just enough pressure so you can feel each beat. Do not push too hard or you will obstruct the blood flow.

When should you not do carotid massage?
Absolute contraindications to carotid sinus massage include myocardial infarction, transient ischemic attack or stroke within the preceding three months. A history of ventricular fibrillation or tachycardia, or a previous adverse reaction to carotid sinus massage are also absolute contraindications.
Does carotid massage increase blood pressure?
In short, the increase in blood pressure in carotid sinus will stimulate stretch receptors, which leads to reflex bradycardia and systemic vasodilatation. The baroreceptor reflex is also critical in maintaining heart rate and blood pressure during postural changes.
Does carotid sinus massage increase heart rate?
limb of the carotid sinus reflex reaches the sympathetic and parasympathetic nervous system of the heart and the peripheral vasculature. Stimulation of the carotid sinus slows the heart rate and may prolong atrioventricular conduction time [ 1.21.
