CARDIAC SOUNDS Meaning and
Definition
-
Cardiac sounds refer to the audible sounds produced by the functioning and movement of the heart. These sounds, also known as heart sounds or cardiac murmurs, are crucial in determining the overall health and condition of the heart. They can be heard using a stethoscope and are created by the vibrations and changes in blood flow within the heart chambers and valves during the cardiac cycle.
There are two main components to cardiac sounds: the first heart sound (S1) and the second heart sound (S2). S1 is produced by the closure of the heart's mitral and tricuspid valves during ventricular contraction. It is typically described as a "lubb" sound and marks the beginning of systole. S2 is created by the closure of the aortic and pulmonary valves during the beginning of diastole and is usually described as a "dubb" sound. These two heart sounds are crucial in determining the presence of any abnormalities or irregularities in the heart's structure and function.
Abnormal cardiac sounds can indicate various heart conditions, including valve disorders, heart murmurs, and heart defects. Additional heart sounds, known as S3 and S4, may also be present in certain conditions and can provide important diagnostic information.
Overall, cardiac sounds serve as a valuable diagnostic tool for healthcare professionals in assessing the overall function and health of the heart, helping to identify potential abnormalities and guiding appropriate treatment interventions.
