A These are normal heart sounds. S1 is the closure of the tricuspid and mitral
valves, and S2 is the closure of the pulmonic and aortic valves.
B S3 is a normal heart sound sometimes heard in children. S4 is rarely heard as a
normal heart sound. If heard, medical evaluation is required.
C Murmurs are the sounds that are produced in the heart chambers or major arteries
from the purulence of blood flow. Murmurs create a blowing and swooshing
sound.
D Physiologic splitting is the distinction of the two sounds in S2, which widens on
inspiration. It is a significant normal finding.
