| venous murmur | A murmur heard over a vein. (05 Mar 2000) |
| vesicular murmur | The respiratory murmur heard on auscultating over the normal lung. Synonym: respiratory murmur, vesicular murmur. (05 Mar 2000) |
| Gibson murmur | The typical continuous "machinery-like" murmur of patent ductus arteriosus. (05 Mar 2000) |
| regurgitant murmur | A murmur due to leakage or backward flow at one of the valvular orifices of the heart. (05 Mar 2000) |
| 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.

| mitral murmur | A murmur produced at the mitral valve, either obstructive or regurgitant. (05 Mar 2000) |
| 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) |
