The nurses auscultated for heart sounds in the area of Erb point.
The fifth point of auscultation for the heart test, known as "Erb's point," which is occasionally given to the eminent German neurologist Wilhelm Heinrich Erb (1840–1921) without any supporting documentation, is positioned in the third intercostal gap near the sternum. At the third intercostal gap and the left lower sternal border is the auscultation location for heart sounds and heart murmurs known as Erb's point.
The spinal accessory nerve in the posterior nerve triangle is located at Erb's point (also known as the great auricular nerve) at the location where it enters the trapezius muscle. At the end of expiration, the third intercostal gap on the left (Erb's point) is often the ideal place to detect the murmur of aortic regurgitation because it is quiet, high-pitched, early diastolic and decrescendo.
