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 ...

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.
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 ...
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
Auscultation (based on the Latin verb auscultare "to listen") is listening to the internal sounds of the body, usually using a stethoscope. Auscultation is performed for the purposes of examining the circulatory and respiratory systems (heart and breath sounds), as well as the alimentary canal. The term was introduced by René Laennec. The act ...
