Systolic Murmur Pitch










Systolic Murmur Pitch
The pitch of a murmur is also important. Large pressure gradients between cardiac chambers cause higher pitch murmurs than those that occur when the pressure differential is less. The pressure generated when the left ventricle contracts and forces blood over a stenotic aortic valve is higher than when blood in diastole flows over a stenotic mitral valve. Consequently aortic stenosis has a higher pitched murmur than does mitral stenosis.
The following sound illustrates example of a low pitched systolic murmur:







This is an example of a high pitched or musical early systolic murmur:
