Carotid bruit are discovered incidentally in an otherwise asymptomatic patient. The presence of a carotid bruit alone does not necessarily indicate the presence of stenosis, and the physical examination cannot be used to estimate the degree of stenosis, if present; therefore, any bruit must be evaluated by ultrasound or imaging. Bruit is traditionally pronounced "broot", rhyming with "boot", although the etymologically accurate pronunciation "bru´e" or "bru-e´" is common in North American medical parlance. In addition, while "bruit" and "murmur" are technically synonymous, the term "bruit" is generally reserved for arterial sounds in North America. Carotid bruit A carotid bruit is a vascular
Carotid sinus the carotid sinus reflex when pressure builds in one or both carotid sinuses. Stimulation of baroreceptors at the carotid sinus can be used to treat resistant hypertension via activation of the baroreflex. A pacemaker-like device can be implanted to electrically stimulate the receptors chronically, which is found to lower blood pressure by 15-25 mmHg. 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 therapy for SVT. It is less effective than pharmaceutical management of SVT
