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. [1]
Still's murmur is detected via auscultation with a stethoscope.It has a peculiar "musical", "resonant" or "vibratory" quality that is quite unique. [1] [2] It is generally most easily heard at the left middle or lower sternal border and the right upper sternal border, often with radiation to the carotid arteries, although other locations are common.
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. [1] This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. [2] The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing.
The loudness of the murmur does not correlate well with the severity of regurgitation. It may be followed by a loud, palpable P 2, [6] heard best when lying on the left side. [7] A third heart sound is commonly heard. [6] Patients with mitral valve prolapse may have a holosystolic murmur or often a mid-to-late systolic click and a late systolic ...
A pansystolic heart murmur may be heard on auscultation of the chest. The murmur is usually of low frequency and best heard on the lower left sternal border. It increases with inspiration, and decreases with expiration: this is known as Carvallo's sign. However, the murmur may be inaudible due to the relatively low pressures in the right side ...

A Cabot–Locke murmur [1] is an early diastolic heart murmur, occasionally heard in severe untreated anemia, without heart valve abnormalities. [2] It is detected infrequently, is best heard at the left sternal border, and sounds similar to aortic insufficiency , although it is without decrescendo .
Heart murmurs need to be distinguished from heart sounds which are primarily generated by the beating heart and the heart valves snapping open and shut. Generally, heart murmurs are classified as innocent (also called physiological or functional) or pathological (abnormal). Innocent murmurs are usually harmless, often caused by physiological ...
