cardiac auscultation

Cardiac auscultation is a medical technique where a doctor listens to the sounds of the heart using a stethoscope. The heart produces sounds during its cycles, typically described as "lub" (S1) and "dub" (S2). These sounds indicate the opening and closing of heart valves, and the doctor assesses their quality to detect any irregularities or issues, such as heart murmurs or abnormal rhythms. It's a fundamental part of a heart examination, helping healthcare professionals assess heart health and diagnose potential problems without invasive procedures.
