one of a number of abnormal heart sounds; consists of a flow noise that is heard before the normal lubb-dupp or that may mask normal heart sounds
An abnormal sound heard when the heart beats. This sound may result simply from increased blood flow in the heart-the murmur is termed physiological and is not considered serious. Other murmurs are caused by blood flowing through abnormal openings in the heart (such as a patent foramen ovale) or through an abnormal heart valve (such as aortic stenosis).
