a nonvalvular murmur heard on auscultation of the heart and large blood vessels in cases of profound anemia associated mainly with turbulent blood flow resulting from decreased blood viscosity.
a·ne·mic mur·mur(ă-nē'mik mŭr'mŭr)
murmur(mur'mur) [L. 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
anemic murmurHemic 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
aortic obstructive murmur
A harsh systolic murmur heard with and after the first heart sound. It is loudest at the base.
aortic regurgitant murmur
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.
Austin Flint murmurSee: 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.
Cruveilhier-Baumgarten murmurSee: Cruveilhier-Baumgarten murmur
A murmur occurring during relaxation of the heart.
Duroziez' murmurSee: 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.
extracardiac murmurExocardial 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.

heart murmurCardiac murmur.
A sound heard on auscultation of anemic persons without valvular lesions and resulting from an abnormal, usually anemic, blood condition.
holosystolic murmurPansystolic murmur.
machinery murmurGibson'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 changes.
A heart murmur heard throughout systole.
A friction sound produced within the pericardium.
physiologic murmurFunctional murmur.
prediastolic murmurSystolic 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.
Still's murmurSee: 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.
an auscultatory sound, particularly a periodic sound of short duration of cardiac or vascular origin.
see blood murmur (below).
a sound indicative of disease of the aortic valve.
one heard over the apex of the heart.
one in an artery, sometimes aneurysmal and sometimes constricted.
one due to an abnormal, commonly anemic, condition of the blood. Called also anemic murmur.
see heart murmur (below).
one produced by the impact of the heart against the lung.
a humming murmur heard throughout systole and diastole.
one marked by progressively increasing loudness.
one with increasing intensity until mid- to late systole, then a decreasing intensity, giving a diamond-shaped tracing on phonocardiography. Characteristic of pulmonary stenosis.
one with an intensity that gradually decreases. Heard during diastole in aortic or pulmonary valvular insufficiency.
refers to the phonocardiographic tracing of a crescendo-decrescendo murmur.
one at diastole, due to mitral obstruction or to aortic or pulmonary regurgitation.
systolic murmur heard predominantly in mid-systole, when ejection volume and velocity of blood flow are at their maximum.
a cardiac murmur occurring in the absence of structural changes in the heart.
any adventitious sound heard over the region of the heart. It may indicate a leaking or stenotic valve, a congenital patency between the right and left sides of the heart, or be a functional murmur which does not indicate cardiac disease. These occur in young foals, some of them disappear before maturity.
see blood murmur (above).
one caused by increased velocity of blood rather than a cardiac lesion.
machinery murmur, machinery-like murmur
a long, rumbling sound occupying most of systole and diastole. Characteristic of patent ductus arteriosus and arteriovenous fistulas.
one due to disease of the mitral valve.
a cardiac murmur having a periodic harmonic pattern.
one due to structural change in the heart.
one heard throughout systole.
one occurring just before and with diastole, due to mitral obstruction or to aortic or pulmonary regurgitation.
one occurring shortly before the onset of ventricular ejection, usually associated with a narrowed atrioventricular valve.
one due to disease of the valves of the pulmonary artery.
radiating heart murmur
one which is heard over a wider area or over another area. The systolic murmur of subaortic stenosis radiates up the aortic arch and carotid arteries. It can be heard over the right, as well as left, heart base and occasionally over the head.
one due to a dilated valvular orifice, with consequent regurgitation of blood through the valve.
a raucous murmur resembling the call of a seagull, frequently heard in aortic insufficiency.
one occurring at systole, usually due to mitral or tricuspid regurgitation, or to aortic or pulmonary obstruction.
one caused by disease of the tricuspid valve.
one heard over a blood vessel.
the normal breath sounds heard over the lungs.
