murmur

aortic murmur a sound indicative of disease of the aortic valve.

apex murmur (apical murmur) a heart murmur heard over the apex of the heart.

arterial murmur one in an artery, sometimes aneurysmal and sometimes constricted.

Austin Flint murmur a loud presystolic murmur at the apex heard when aortic regurgitation is preventing the mitral valve from closing; called also Flint's murmur.

blood murmur one due to an abnormal, commonly anemic, condition of the blood. Called also hemic murmur.

cardiac murmur heart murmur.

cardiopulmonary murmur one produced by the impact of the heart against the lung.

continuous murmur a humming heart murmur heard throughout systole and diastole.

crescendo murmur one marked by progressively increasing loudness that suddenly ceases.

Cruveilhier-Baumgarten murmur one heard at the abdominal wall over veins connecting the portal and caval systems.

diastolic murmur a heart murmur heard at diastole, due to mitral obstruction or to aortic or pulmonic regurgitation with forward flow across the atrioventricular valve; it has a rumbling quality.

Duroziez's murmur a double murmur during systole and diastole, palpated over the femoral or another large peripheral artery; due to aortic insufficiency.

ejection murmur a systolic murmur heard predominantly in midsystole, when ejection volume and velocity of blood flow are at their maximum; it is produced by ejection of blood into the pulmonary artery and aorta.

Flint's murmur Austin Flint murmur.

friction murmur friction rub.

functional murmur a heart murmur occurring in the absence of structural changes in the heart, usually due to high cardiac output states. Called also innocent murmur and physiologic murmur.

Gibson murmur a long rumbling sound occupying most of systole and diastole, usually localized in the second left interspace near the sternum, and usually indicative of patent ductus arteriosus. Called also machinery murmur.

Graham Steell murmur a high-pitched diastolic murmur due to pulmonic regurgitation in patients with pulmonary hypertension and mitral stenosis.

heart murmur see heart murmur.

hemic murmur blood murmur.

innocent murmur functional murmur.

machinery murmur Gibson murmur.

mitral murmur a heart murmur due to disease of the mitral valve; it can be either obstructive or regurgitant.

musical murmur one that has a periodic harmonic pattern; it may be either a heart murmur or a vascular murmur.

organic murmur one due to a lesion in the organ or organ system being examined, e.g., in the heart, in a blood vessel, or in lung tissue.

pansystolic murmur a regurgitant murmur heard throughout systole, due to blood flow between two chambers normally of very different pressures in systole; the most common causes are mitral regurgitation, tricuspid regurgitation, and ventricular septal defects.

physiologic murmur functional murmur.

prediastolic murmur one occurring just before and with diastole, due to aortic regurgitation or pulmonic regurgitation.

presystolic murmur one shortly before the onset of ventricular ejection, usually associated with a narrowed atrioventricular valve.

pulmonic murmur one due to disease of the pulmonary valve or artery.

regurgitant murmur a heart murmur due to a dilated valvular orifice with consequent valvular regurgitation.

seagull murmur a raucous murmur resembling the call of a seagull, frequently heard in aortic stenosis or mitral regurgitation.

Still's murmur a functional heart murmur of childhood, with a buzzing or vibratory tone heard in midsystole; it usually disappears by puberty.

systolic murmur a heart murmur heard at systole, usually due to mitral or tricuspid regurgitation or to aortic or pulmonary obstruction.

to-and-fro murmur a friction sound or murmur heard with both systole and diastole.

tricuspid murmur a heart murmur caused by disease of the tricuspid valve; it may be either obstructive or regurgitant.

vascular murmur one heard over a blood vessel.

vesicular murmur vesicular breath sounds.

An abnormal heart sound that can reflect a valve dysfunction.

A. A heart murmur is a sound that is created by inadequate blood flow through the heart and its large vessels, for example the aorta. Some are born with a heart murmur and further testing doesn't reveal any significant problem. This is called a physiological murmur.

A. Heart murmurs are charachterized by their location, their strength, their timing, whether or not they radiate and so on. For example, this is a sound of a heart murmur compatible with a disease called aortic stenosis-

Notice that the murmur begin with the heart sound and lasts all through the beat.
