Time Condition Description Early diastolic Aortic regurgitation: The murmur is low intensity, high-pitched, best heard over the left sternal border or over the right second intercostal space, especially if the patient leans forward and holds breath in full expiration.
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.
Heart murmurs are produced as a result of turbulent flow of blood strong enough to produce audible noise. They are usually heard as a whooshing sound. The term murmur only refers to a sound believed to originate within blood flow through or near the heart; rapid blood velocity is necessary to produce a murmur.
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.
S 3 is a dull, low-pitched sound best heard with the bell placed over the cardiac apex with the patient lying in the left lateral decubitus position. This heart sound when present in a child or young adult implies the presence of a supple ventricle that can undergo rapid filling.
In cardiology, an Austin Flint murmur is a low-pitched rumbling heart murmur which is best heard at the cardiac apex. [1] It can be a mid-diastolic [2] or presystolic murmur. [3] It is associated with severe aortic regurgitation, although the role of this sign in clinical practice has been questioned. [4]
A mid-diastolic rumbling murmur with presystolic accentuation will be heard after the opening snap. [3] [11] The murmur is best heard at the apical region and is not radiated. Since it is a low-pitch sound, it is heard best with the bell of the stethoscope. [3] Its duration increases with worsening disease. [3]
Another finding is an opening snap followed by a low-pitched diastolic rumble with presystolic accentuation. [16] [15] The opening snap follows closer to the S 2 heart tone with worsening stenosis. [16] The murmur is heard best with the bell of the stethoscope [16] lying on the left side [15] and its duration increases with worsening disease. [16]
