The murmur is audible with the stethoscope not touching the chest but lifted just off it. The Levine scaling system persists as the gold standard for grading heart murmur intensity. It provides accuracy, consistency, and interrater agreement which are essential for diagnostic purposes, particularly to distinguish innocent from pathological murmurs.
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 ...

The Means–Lerman scratch is an uncommon type of heart murmur which occurs in patients with hyperthyroidism. It is a mid-systolic scratching sound best heard over the upper part of the sternum or second left intercostal space at the end of expiration . [ 1 ]
Auscultogram from normal and abnormal heart sounds. 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.
A Wiggers diagram modified from [1]. A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century.
