Both components of S2 (A2 and P2) are usually well transmitted to the Erb's point. The physiological splitting of S2 into A2 and P2 is believed to be appreciated best at the Erb's point or in the pulmonic area. A2 is best heard over the aoic area in the right second intercostal space P2 is best heard over the pulmonic area in the left second intercostal space Second hea sound (S2) is best heard over the pulmonic area (Since both A2 and P2 can be heard at the pulmonic area) and at the Erb's Point. Note that even at the pulmonic area A2 is louder than P2 1. Aoic area Second intercostal space to the right of the sternum (along right upper sternal border) 2.
