Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...
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. Louder murmurs (grade ≥3) are more likely believed to represent cardiac defects ...

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.
Computer-aided auscultation (CAA), or computerized assisted auscultation, is a digital form of auscultation. It includes the recording, visualization, storage, analysis and sharing of digital recordings of heart or lung sounds. The recordings are obtained using an electronic stethoscope or similarly suitable recording device.
A gallop rhythm refers to a (usually abnormal) rhythm of the heart on auscultation. [1] It includes three or four sounds, thus resembling the sounds of a gallop.. The normal heart rhythm contains two audible heart sounds called S 1 and S 2 that give the well-known "lub-dub" rhythm; they are caused by the closing of valves in the heart.
