text: A<unk>  is a<unk>  or sound heard over the carotid artery area, usually by a nurse or physician during auscultation. It is usually the result of a stenosis of the carotid artery, and is unlikely to be heard if the stenosis occludes less than 40% of the diameter of the artery. Likewise, a stenosis of greater than 90% may not be heard, as the flow may be too low.
