Relation of Auscultatory Findings to the Chest Wall

The locations on the chest wall where you hear heart sounds and murmurs help to identify the valve or chamber where they originate. Sounds and murmurs arising from the mitral valve are usually heard best at and around the cardiac apex. Those originating in the tricuspid valve are heard best at or near the lower left sternal border. Murmurs arising from the pulmonic valve are usually heard best in the 2nd and 3rd left interspaces close to the sternum, but at times may also be heard at higher or lower levels, and those originating in the aortic valve may be heard anywhere from the right 2nd interspace to the apex. These areas overlap, as illustrated below, and you will need to correlate auscultatory findings with other portions of the cardiac examination to identify sounds and murmurs accurately.
