Auscultation of heart, its changes and impacts on the cardiac pathophysiology: A descriptive review

Only after a comprehensive examination of the precordium may one begin an auscultation of the heart. Inspection, palpation, percussion, and auscultation are all steps in the precordium examination procedure. Here, we only go into detail on cardiac auscultation. Heart sounds and murmurs are extremely hard to hear without the right equipment because their amplitude and frequency signals are so tiny. You may listen to heart sounds by placing your ear over your chest, using a stethoscope, or using a microphone. Graphics are also recorded for the sounds. The four auscultatory areas in our precordium region are the mitral area, tricuspid area, aortic area, and pulmonary area. Heart sounds has significant diagnostic significance in clinical practise because changes in heart sounds are indicative of heart valve dysfunction. With the use of a stethoscope or microphone, one may hear four different heart sounds: the first heart sound (LUB), also known as s1, the second heart sound (DUB), also known as s2, the third heart sound (s3), and the fourth heart sound (s4). Every normal person can hear their first and second heart sounds, but only those with abnormal cardiac issues can hear their third and fourth heart sounds. With the use of a stethoscope, murmurs may also be heard.
