Murmurs are the sounds that are produced in the heart chambers or major arteries from the back-and-forth flow of blood.S₁ is the closure of the tricuspid and mitral valves,and S₂ is the closure of the pulmonic and aortic valves; both are considered normal heart sounds.S₃ is a normal heart sound sometimes heard in children.S₄ is rarely heard as a normal heart sound,and a medical evaluation is required if the nurse hears it.Physiological splitting is the distinction of the two sounds in S₂,which widens on inspiration.It is a significant normal finding.
