👉 The stethoscope, a device used for auscultation (a medical procedure that listens to the sounds made by the heart), is defined as a tool or instrument used in medicine and surgery, specifically for assessing the quality of sound produced during the heartbeat. It's typically worn on one ear and can detect various heart conditions such as arrhythmias, ventricular tachycardia, bradycardia, and other heart rhythms.
