| cooing murmur | A murmur, usually of mitral regurgitation, of very high pitch resembling the cooing of a pigeon or a dove. (05 Mar 2000) |
|---|---|
| Coombs murmur | A blubbering apical middiastolic murmur occurring in the acute stage of rheumatic mitral valvulitis and disappearing as the valvulitis subsides. Synonym: Coombs murmur. (05 Mar 2000) |
| musical murmur | A cardiac or vascular murmur having a high-pitched musical character. (05 Mar 2000) |
| crescendo murmur | A murmur that increases in intensity and suddenly ceases; the presystolic murmur of mitral stenosis is a common example. (05 Mar 2000) |
| Cruveilhier-Baumgarten murmur | A venous murmur heard over collateral veins, connecting portal and caval venous systems, on the abdominal wall. See: Cruveilhier-Baumgarten sign. (05 Mar 2000) |
| Hamman's murmur | A crunching precordial sound synchronous with the heart beat; heard in mediastinal emphysema. (05 Mar 2000) |
| presystolic murmur | A murmur heard at the end of ventricular diastole (during atrial systole if in sinus rhythm), usually due to obstruction at one of the atrioventricular orifices. Synonym: atriosystolic murmur, late diastolic murmur. (05 Mar 2000) |
| heart murmur | A finding on physical examination of the heart that can, in some cases, indicate the presence of cardiac disease. Murmurs result from vibrations set up in the bloodstream and the surrounding heart and great vessels as the result of turbulent flow. (27 Sep 1997) |
| hemic murmur | A cardiac or vascular murmur heard in anaemic persons who have no valvular lesion, probably due to the increased blood velocity and turbulence that characterises anaemia. (05 Mar 2000) |
| sea gull murmur | A murmur imitating the cooing sound of a seagull nearly always due to aortic stenosis or mitral regurgitation. (05 Mar 2000) |
| Hodgkin-Key murmur | <cardiology, clinical sign> A musical diastolic murmur associated with retroversion of an aortic cusp; often very loud. (05 Mar 2000) |
| holosystolic murmur | A murmur occupying the entire systolic interval, from first to second heart sounds. Synonym: holosystolic murmur. (05 Mar 2000) |
| seesaw murmur | Murmur heard in both systole and diastole of the heart, as in aortic stenosis and insufficiency. Synonym: seesaw murmur. (05 Mar 2000) |
| pulmonary murmur | A murmur produced at the pulmonary orifice of the heart, either obstructive or regurgitant. (05 Mar 2000) |
| hourglass murmur | One in which there are two areas of maximum loudness decreasing to a point midway between the two. (05 Mar 2000) |
