This article focuses on the practical use of the stethoscope. The art of the cardiac physical examination includes skillful auscultation. The article provides the author's personal approach to the patient for the purpose of best hearing, recognizing, and interpreting heart sounds and murmurs. It should be used as a brief introduction to the art of auscultation.
