<prompt> Erbs Point in cardiology refers to:Right 2nd intercostal spaceLeft 2nd intercostal spaceRight 3rd intercostal spaceLeft 2nd intercostal space  <response>: Answer is C Right 3rd intercostal space In cardiology, Erbs point refers to the third intercostal space on the left sternal border where both components of S2 A2 and P2 can be well appreciated. Both components of S2 A2 and P2 are usually well transmitted to the Erbs point. The physiological splitting of S2 into A2 and P2 is believed to be appreciated best at the Erbs 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 Erbs 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.
