Heart Murmur

Heart Murmur Definition

Definition

A heart murmur is an abnormal sound made by turbulent blood flow in the heart. Some adults and many children have incidental heart murmurs that are harmless (benign). At least 30% of children may have an innocent heart murmur at some point during childhood. However, some heart murmurs can signal an underlying heart problem.
