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.
Still ' s murmur (also known as vibratory murmur) is a common type of benign or "innocent" functional heart murmur that is not associated with any sort of cardiac disorder or any other medical condition. [1] It can occur at any age although it is most common among children two to seven years of age and it is rare in adulthood. [2]
The little girl, who has a heart murmur and complications after a bad bout of bronchitis, had been covered by Medicaid, the government program insuring low-income and disabled Americans.
Turbulence may occur inside or outside the heart; if it occurs outside the heart then the turbulence is called bruit or vascular murmur. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it.
A murmur is an extra heart sound that can be heard by a stethoscope. Sometimes, a murmur sounds like a humming sound, which can be faint or loud. It might be temporary or persistent.
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 ...
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 ]
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 of the heart.
