| IM | idiopathic myelofibrosis; immunosuppressive method; implementation monitoring; Index Medicus; indome... |
| LSM | late systolic murmur; lymphocyte separation medium; lysergic acid morpholide |
| MDM | medical decision making; mid-diastolic murmur; minor determinant mix [penicillin] |
| MER | mean ejection rate; medical emergency room; methanol extraction residue; murmur/energy ratio |
| respiratory murmur | The respiratory murmur heard on auscultating over the normal lung. Synonym: respiratory murmur, vesicular murmur. (05 Mar 2000) |
|---|---|
| pericardial murmur | A friction sound, synchronous with the heart movements, heard in certain cases of pericarditis. (05 Mar 2000) |
| Graham Steell's murmur | <cardiology, clinical sign> An early diastolic murmur of pulmonary insufficiency secondary to pulmonary hypertension, as in mitral stenosis and various congenital defects associated with pulmonary hypertension. Synonym: Steell's murmur. (05 Mar 2000) |
| Roger's murmur | A loud pansystolic murmur maximal at the left sternal border, caused by a small ventricular septal defect. Synonym: bruit de Roger, Roger's bruit. (05 Mar 2000) |
| middiastolic murmur | A murmur beginning after the A-V valves have opened in diastole, i.e., an appreciable time after the second heart sound, as the murmur of mitral stenosis. (05 Mar 2000) |
| mill wheel murmur | Churning cardiac murmur produced by air embolism to the heart; also heard in pneumohydropericardium. Synonym: water wheel murmur. (05 Mar 2000) |
| click-murmur syndrome | <syndrome> Mitral valve prolapse (also known as Barlow's syndrome ), the most common heart valve abnormality, affecting 5-10% of the world population. Most patients have no symptoms and require no treatment, but some have fatigue and/or palpitations. The mitral valve prolapse can often be detected by a doctor during examination of the heart and confirmed with an echocardiogram. Patients are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery, because of an increased risk of infection of the abnormal heart valve.

| Cole-Cecil murmur | The diastolic murmur of aortic insufficiency when well or predominantly heard in the left axilla. (05 Mar 2000) |
| water wheel murmur | Churning cardiac murmur produced by air embolism to the heart; also heard in pneumohydropericardium. Synonym: water wheel murmur. (05 Mar 2000) |
| pleuropericardial murmur | A pleural friction sound over the pericardial region, synchronous with the heart's action, and simulating a pericardial murmur (rub). (05 Mar 2000) |
| 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) |
| continuous murmur | A murmur that is heard without interruption throughout systole and into diastole. (05 Mar 2000) |
| 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) |
