Next part of the cardiac examination is the listening or auscultation of the heart itself. When listening to the heart sounds the examiner first must landmark appropriately and understands what they are listening to. Listening to the heart takes years of experience to pick up the nuances of the heart sounds. By the time the doctor and nurse graduate they have sufficient experience. The examiner places the stethoscope over 4 areas of the chest to listen to the valves of the heart to pick up a possibility of heart murmurs. To listen to the pulmonary valve the stethoscope is placed over the second intercostal space (the space between the 2nd and 3rd rib) left side of the patientâs sternum.
