How to auscultate for heart sounds in adults

This article aims to improve nurses’ knowledge and understanding of the procedure for auscultating heart sounds in adults, as part of a cardiovascular examination. It focuses on auscultating normal heart sounds; it is beyond the scope of this article to discuss the pathophysiology of abnormal findings.
A stethoscope is used to auscultate for heart sounds. The diaphragm of the stethoscope is used to identify high-pitched sounds, while the bell is used to identify low-pitched sounds.
There are two normal heart sounds that should be elicited in auscultation: S1 (lub) and S2 (dub).
The practitioner should listen over each of the four main heart valve areas: the aortic, pulmonary, tricuspid and mitral valve areas. They should also listen for any additional sounds such as clicks, and heart murmurs.
