|---|
| crescendo angina | Angina pectoris that occurs with increasing frequency, intensity, or duration. (05 Mar 2000) |
|---|---|
| crescendo sleep | Normal sleep, marked by a gradual increase in movements of the sleeper during the course of the night. (05 Mar 2000) |
| accidental murmur | An evanescent cardiac murmur not due to valvular lesion. (05 Mar 2000) |
| anaemic murmur | A nonvalvular murmur heard on auscultation of the heart and large blood vessels in cases of profound anaemia associated mainly with turbulent blood flow due to decreased blood viscosity. (05 Mar 2000) |
| aneurysmal murmur | A systolic or systolic-diastolic murmur heard over some cardiac aneurysms. (05 Mar 2000) |
| aortic murmur | A murmur produced at the aortic orifice, either obstructive or regurgitant. (05 Mar 2000) |
| arterial murmur | A murmur heard on auscultating an artery. (05 Mar 2000) |
| atriosystolic 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) |
| Austin Flint murmur | Synonym: Austin Flint phenomenon, Flint's murmur. (05 Mar 2000) |
| bellows murmur | A blowing murmur. (05 Mar 2000) |
| brain murmur | <neurology> Sounds produced by intracranial aneurysms or arterial venous aneurysms in congenital dysplastic angiomatosis. (05 Mar 2000) |
| Cabot-Locke murmur | <cardiology, clinical sign> An early diastolic murmur, like that of aortic insufficiency, heard best at the left lower sternal border in severe anaemia. (05 Mar 2000) |
| cardiac murmur | A murmur produced within the heart, at one of its valvular orifices or across ventricular septal defects. (05 Mar 2000) |
| cardiopulmonary murmur | <cardiology, clinical sign> An innocent extracardiac murmur, synchronous with the heart's beat but disappearing when the breath is held, believed due to movement of air in a segment of lung compressed by the contracting heart. Synonym: cardiorespiratory murmur. (05 Mar 2000) |
