A P T M:
The aortic valve is located at the right 2nd intercostal mid sternum (next to breast bone).
The Pulmonic is located at the left 2nd intercostal mid sternum (next to breast bone).
The tricuspid is located at the left 4th intercostal space (next to breast bone).
The mitral (aka Apex) is located at the left 5th mid clavicular intercostal space (look at mid clavical area) but of course is measured at the 5th intercostal space.
You can hear the S1 and S2 sounds at the 4th and 5th left intercostal space and easier to hear if the patient is lying on their left side.
Keep in mind that if a patient has cardiomegaly from heart damage, the apex may be heard more laterally towards the side.

Could anyone help me identify landmarks on where the sounds of S1 and all that are heard and which side, what location is aortic, pulmonic, tricuspid, mitral valves. Where the apex is, where PMI is? I've been looking in books for a diagram and picture and can't find one.
Please help:o
