Appearance move to sidebar hide From Wikipedia, the free encyclopedia Abnormal sound from turbulent arterial blood flow Medical condition

Bruit
Other names	Vascular murmur
Pronunciation	English: /ˈbruːt/, /ˈbruːi/[1][2]
Specialty	Cardiology

Bruit, also called vascular murmur,[3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.[4]

The bruit may be heard ("auscultated") by securely placing the head of a stethoscope to the skin over the turbulent flow, and listening. Most bruits occur only in systole, so the bruit is intermittent and its frequency dependent on the heart rate. Anything increasing the blood flow velocity such as fever, anemia, hyperthyroidism, or physical exertion, can increase the amplitude of the bruit.

Etymology

[edit]

It is naturalized from the French word for "noise", although another notes that /ˈbruːi/ and /bruːˈiː/ are also common,[5] and others give only /ˈbruːi/ for the cardiac sense.[6][7]
