User avatar Dear Fearuvhorses,

An s3 is an additional sound that is heard on auscultation of the heart.

Normally, there are s1 (the first heart sound) and s2 (the second heart sound).

An s3 may be a normal finding in infants and young healthy adults and some cases of increased cardiac output. After the age of 40 years it is considered abnormal.

It is usually an indication of heart failure.

Thank you very much for using our website https://doctorslounge.com and i hope that this information helped.

Yasser Mokhtar, M.D.
