HEART SOUND Meaning and
Definition
-
Heart sound refers to the distinct sounds produced by the beating heart as blood flows through the chambers and valves. These sounds, also known as cardiac sounds or cardiac auscultation, can be heard through a stethoscope placed on the chest wall. The heart generates two main sounds, commonly referred to as the "lub-dub" sound. The first sound, "lub," is caused by the closure of the atrioventricular valves (mitral and tricuspid) during systole, when the ventricles contract and blood is pumped out of the heart. The second sound, "dub," is produced by the closure of the semilunar valves (aortic and pulmonary) during diastole, when the heart is relaxed and receiving blood from the atria.
These heart sounds provide crucial information about the functioning of the heart and are used in diagnosing various cardiac conditions. An abnormality in the intensity, timing, or pitch of the heart sounds can indicate an underlying problem, such as valve abnormalities, heart murmurs, or heart failure. Additional sounds, called murmurs, can also be heard during auscultation, which may indicate turbulent blood flow through narrowed or leaky valves.
The interpretation of heart sounds requires proper training and experience, as subtle variations can provide valuable insights into a patient's cardiac health. Different maneuvers, such as changing body positions or applying pressure to the chest, may be used to amplify certain heart sounds or reveal specific abnormalities. Therefore, accurate assessment of heart sounds is vital for a comprehensive cardiovascular examination and assists in the diagnosis and management of cardiac conditions.

Etymology of HEART SOUND
The word "heart sound" is composed of two individual words: "heart" and "sound".
- "Heart" originated from the Old English word "heorte", which can be traced back to the Proto-Germanic word "khertan". It is thought to be derived from the Indo-European root "kerd", meaning "heart".
- "Sound" came from the Old English word "swē̆gen", which itself is related to the Proto-Germanic word "swōgan" and the Proto-Indo-European root "swēg" meaning "to sound, resound".
Combining these two words, "heart sound" refers to the audible noises produced by the heart during its normal functioning.
