(mŭr′mŭr)
[L. murmur, a humming, growling, murmur]
An abnormal sound or extra beat heard when listening to the heart or neighboring large blood vessels. Murmurs may be soft, blowing, rumbling, booming, loud, or variable in intensity. They may be heard during systole, diastole, or both. A murmur does not necessarily indicate heart disease, and many heart diseases do not produce murmurs.
SEE: heart
SEE: Hemic murmur.
A whizzing systolic sound heard over an aneurysm. It is more commonly known as a bruit.
An abnormal, soft sound heard on auscultation that may be due to stenosis or regurgitation. It is a sign of aortic valvular disease.
SEE: aortic regurgitant murmur
A harsh systolic murmur heard with and after the first heart sound. It is loudest at the base.
A blowing or hissing following the second heart sound.
An inorganic murmur over the apex of the heart.
A soft flowing murmur that is synchronous with the pulse.
SEE: Austin Flint murmur
A murmur heard over large bronchi, resembling respiratory laryngeal murmur.
A sound arising due to blood flow through the heart.
A murmur caused by movement of the heart against the lungs.
A murmur that extends throughout systole and diastole.
A murmur that progressively builds up in intensity and then suddenly subsides.
A murmur occurring during relaxation of the heart.
SEE: Duroziez' murmur
A systolic murmur that is most intense at the time of maximum flow of blood from the heart. This murmur is associated with pulmonary and aortic stenosis.
An abnormal sound produced by any cause and arising within the heart.
A cardiac murmur produced outside the cavities of the heart.
SEE: Exocardial murmur.
A murmur caused by an inflamed mucous surface rubbing against another, as in pericarditis.
A murmur occurring in the absence of any pathological change in the structure of the heart valves or orifices. It does not indicate organic disease of the heart, and may disappear upon a return to health. It may be mistaken for a pathological murmur by an inexperienced listener.
SEE: Gibson's murmur
SEE: Cardiac murmur.
A sound heard on auscultation of anemic persons without valvular lesions and resulting from an abnormal, usually anemic, blood condition.
SEE: Pansystolic murmur.
SEE: Gibson's murmur.
A murmur produced at the orifice of the mitral (bicuspid) valve.
A cardiac murmur with sounds that have an intermittent harmonic pattern.
A murmur due to structural abnormalities in the heart.
A heart murmur heard throughout systole.
A friction sound produced within the pericardium.
SEE: Functional murmur.
SEE: Systolic murmur.
A murmur occurring just before systole, due to mitral or tricuspid obstruction.
A murmur produced at the orifice of the pulmonary artery.
A murmur due to leakage or backward flow of blood through a dilated valvular orifice.
A murmur that resembles the cry of a seagull; sometimes associated with aortic insufficiency.
SEE: Still's murmur
A cardiac murmur during systole.
A pericardial murmur heard during both systole and diastole.
A murmur produced at the orifice of the tricuspid valve and caused by stenosis or incompetency of the valve.
A murmur occurring over a blood vessel.
Normal breath sounds.
