murmur (mur'mur) [L. murmur] An abnormal sound or extra beat heard when listening to the heart or neighboring large blood vessels. Murmurs may be soft, blowing, rumbling, booming, loud, or variable in intensity. They may be heard during systole, diastole, or both. A murmur does not necessarily indicate heart disease, and many heart diseases do not produce murmurs. See: heartanemic murmurHemic murmur.aneurysmal murmurA whizzing systolic sound heard over an aneurysm. It is more commonly known as a bruit. aortic murmurAn abnormal, soft sound heard on auscultation that may be due to stenosis or regurgitation. It is a sign of aortic valvular disease. See: aortic regurgitant murmuraortic obstructive murmurA harsh systolic murmur heard with and after the first heart sound. It is loudest at the base. aortic regurgitant murmurA blowing or hissing following the second heart sound.apex murmurAn inorganic murmur over the apex of the heart.arterial murmurA soft flowing murmur that is synchronous with the pulse.Austin Flint murmur See: Austin Flint murmurbronchial murmurA murmur heard over large bronchi, resembling respiratory laryngeal murmur.cardiac murmurA sound arising due to blood flow through the heart.cardiopulmonary murmurA murmur caused by movement of the heart against the lungs.continuous murmurA murmur that extends throughout systole and diastole.crescendo murmurA murmur that progressively builds up in intensity and then suddenly subsides.Cruveilhier-Baumgarten murmur See: Cruveilhier-Baumgarten murmurdiastolic murmurA murmur occurring during relaxation of the heart.Duroziez' murmur See: Duroziez' murmurejection murmurA systolic murmur that is most intense at the time of maximum flow of blood from the heart. This murmur is associated with pulmonary and aortic stenosis. endocardial murmurAn abnormal sound produced by any cause and arising within the heart.exocardial murmurA cardiac murmur produced outside the cavities of the heart.extracardiac murmurExocardial murmur.friction murmurA murmur caused by an inflamed mucous surface rubbing against another, as in pericarditis.functional murmurA murmur occurring in the absence of any pathological change in the structure of the heart valves or orifices. It does not indicate organic disease of the heart, and may disappear upon a return to health. It may be mistaken for a pathological murmur by an inexperienced listener.
