Heart Murmur
Murmurs are pathologic heart sounds that are produced as a result of turbulent blood flow that is sufficient to produce audible noise. Most murmurs can only be heard with the assistance of a stethoscope ("on auscultation").
A functional murmur or "physiologic murmur" is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself. Functional murmurs are benign (an "innocent murmur").
Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart. Such murmurs, known as pathologic murmurs, should be evaluated by an expert.
Heart murmurs are most frequently categorized by timing, into systolic heart murmurs and diastolic heart murmurs. However, continuous murmurs cannot be directly placed into either category.

Famous quotes containing the words heart and/or murmur:
“Trust thyself: every heart vibrates to that iron string.”
—Ralph Waldo Emerson (1803–1882)
“I believe a man is born first unto himself—for the happy developing of himself, while the world is a nursery, and the pretty things are to be snatched for, and pleasant things tasted; some people seem to exist thus right to the end. But most are born again on entering manhood; then they are born to humanity, to a consciousness of all the laughing, and the never-ceasing murmur of pain and sorrow that comes from the terrible multitudes of brothers.”
—D.H. (David Herbert)
