| Still's murmur | An innocent musical murmur resembling the noise produced by a twanging string; almost exclusively in young children, of uncertain origin and ultimately disappearing. (05 Mar 2000) |
|---|---|
| nun's murmur | <cardiology, clinical sign> A brief or continuous noise originating from the neck veins that may be confused with cardiac murmurs, particularly with the continuous murmur of patent ductus arteriosus. Synonym: bruit de diable, nun's murmur. (05 Mar 2000) |
| systolic murmur | <clinical sign> A sound that is produced by the turbulent flow of blood during the phase of ventricular contraction. The finding of a systolic murmur on physical examination can suggest a heart valve abnormality (for example aortic stenosis, mitral regurgitation, etc.). (27 Sep 1997) |
| diamond-shaped murmur | A crescendo-decrescendo murmur, from the shape of the frequency intensity curve of the phonocardiogram, often audible as such. (05 Mar 2000) |
| diastolic murmur | A murmur heard during diastole. (05 Mar 2000) |
| Duroziez' murmur | A two-phase murmur over peripheral arteries, especially the femoral artery, due to rapid ebb and flow of blood during aortic insufficiency. Synonym: Duroziez' sign. (05 Mar 2000) |
| dynamic murmur | A heart murmur due to anaemia or to any cause other than a valvular lesion. (05 Mar 2000) |
| innocent murmur | A cardiac murmur not associated with a significant heart lesion. Synonym: innocent murmur, inorganic murmur. (05 Mar 2000) |
| inorganic murmur | A cardiac murmur not associated with a significant heart lesion. Synonym: innocent murmur, inorganic murmur. (05 Mar 2000) |
| obstructive murmur | A murmur caused by narrowing of one of the valvular orifices. (05 Mar 2000) |
| organic murmur | A murmur caused by an organic lesion. (05 Mar 2000) |
| early diastolic murmur | A murmur that begins with the second heart sound, as the murmur of aortic insufficiency. (05 Mar 2000) |
| ejection murmur | A diamond-shaped systolic murmur produced by the ejection of blood into the aorta or pulmonary artery and ending by the time of the second heart sound component produced, respectively, by closing of the aortic or pulmonic valve. (05 Mar 2000) |
| to-and-fro murmur | Murmur heard in both systole and diastole of the heart, as in aortic stenosis and insufficiency. Synonym: seesaw murmur. (05 Mar 2000) |
| tricuspid murmur | A murmur produced at the tricuspid orifice, either obstructive or regurgitant. (05 Mar 2000) |
