Decrescendo murmurs decrease in intensity over time. Crescendo-decrescendo murmurs have both shapes over time. These have progressive increase in intensity, peak, and progressive decrease in intensity. Crescendo–decrescendo murmurs resemble a diamond or kite shape. Location refers to where the heart murmur is usually heard best. There are ...
Heart murmurs are sounds generated by blood flowing through the structures of the heart. The location of the Still's murmur on examination suggests resonation of blood in the left ventricular outflow tract and aorta, and this is supported by studies that have shown that the murmur is more intense over the aortic valve than the pulmonary valve.

Heart sounds of a healthy human female with a functional or "innocent" heart murmur after exercise. A functional murmur (innocent murmur, 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.

Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency ( regurgitation ), which allows backflow of blood when the incompetent valve closes with only partial effectiveness.
Systolic heart murmurs are heart murmurs heard during systole, [1] [2] [3] i.e. they begin and end between S1 and S2. Many involve stenosis of the semilunar valves or regurgitation of the atrioventricular valves .
Heart murmurs are most frequently organized by timing, into systolic heart murmurs and diastolic heart murmurs. However, continuous murmurs can not be directly placed into either category. [1] These murmurs are due to blood flow from a high pressure chamber or vessel to a lower pressure system. Patent ductus arteriosus. Patent ductus arteriosus ...
Around 200 of the photos appear in his book, “Murmurations,” which combines the mesmerizing forms with close-ups and scenic shots of Lough Ennell. And while he has long been back documenting ...
Murmurs are graded by volume, from 1 (the quietest), to 6 (the loudest), and evaluated by their relationship to the heart sounds, position in the cardiac cycle, and additional features such as their radiation to other sites, changes with a person's position, the frequency of the sound as determined by the side of the stethoscope by which they ...
