Carotid bruits are systolic sounds associated with turbulent blood flow through atherosclerotic stenosis in the neck. They are audible intermittent high-frequency (above 200 Hz) sounds mixed with background noise and transmitted low-frequency (below 100 Hz) heart sounds that wax and wane periodically.
What causes heart beating sounds?
The familiar ‘lub-dub’ sound of the heartbeat is caused by the rhythmic closing of the heart valves as blood is pumped in and out of the chambers.

Can pulsatile tinnitus cause a stroke?
This abnormal connection forms in the walls of the large veins that return blood from the brain to the heart. The noise occurs due to the flow of high-pressure blood from the arteries to the veins at the base of the skull. These lesions can be low-grade (no danger of stroke) or high-grade.
Is it bad to hear your heartbeat in your ears?

Why does my carotid artery make a swooshing sound?
If a physician detects the abnormal swooshing sound when listening over the carotid artery in the neck with a stethoscope, it is an indication of possible artery blockage and carotid artery disease in the patient. Blocked arteries directly cause the sound. Normal blood flow is smooth and linear, states Cardiovascular Physiology Concepts.
How is tinnitus related to the carotid artery?
Narrowing or kinking in a neck artery (carotid artery) or vein in your neck (jugular vein) can cause turbulent, irregular blood flow, leading to tinnitus. · Malformation of capillaries. A condition called arteriovenous malformation (AVM), abnormal connections between arteries and veins , can result in tinnitus.
