Cardiac Auscultation - Apex

Program Progress:

You are incorrect - our patient's acoustic events at the time of the first heart sound at the apex include a first heart sound, a second heart sound and a third heart sound (S3).

Your choice: S1 + single S2

This is a graphic example of an S1 an a single S2.



The second heart sound at the apex is almost always single and in most normal adults no sound follows a single second sound. Again, in this case, there is an additional sound following the single second heart sound.
