| 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) |
| 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) |
| endocardial murmur | A murmur arising, from any cause, within the heart. (05 Mar 2000) |
| tricuspid murmur | A murmur produced at the tricuspid orifice, either obstructive or regurgitant. (05 Mar 2000) |
| extracardiac murmur | A bruit heard over or near the precordium originating from structures other than the heart; the term includes pericardial friction rubs and cardiopulmonary murmur's. (05 Mar 2000) |
| Flint's murmur | A diastolic murmur, similar to that of mitral stenosis, heard best at the cardiac apex in some cases of free aortic insufficiency; it is thought to be caused by the turbulent regurgitating stream from the aorta mixing into the stream simultaneously entering from the left atrium through the mitral valve, causing posterior movement of the anterior leaflet of the mitral valve with transient acceleration of blood flow through the mitral valve. Synonym: Austin Flint murmur. (05 Mar 2000) |
| Frantzel's murmur | A murmur of mitral stenosis when louder at its beginning and end than in its midportion. (05 Mar 2000) |
| friction murmur | The sound, heard on auscultation, made by the rubbing of two opposed serous surfaces roughened by an inflammatory exudate, or, if chronic, by nonadhesive fibrosis. Synonym: friction murmur, friction rub. (05 Mar 2000) |
| functional murmur | A cardiac murmur not associated with a significant heart lesion. Synonym: innocent murmur, inorganic murmur. (05 Mar 2000) |
