Heart murmur – Definition

A heart murmur is an abnormal sound made by turbulent blood flow in the heart. It sounds like whooshing or swishing with each heartbeat. Some adults and many children have incidental heart murmurs that are harmless (benign) and are not caused by abnormalities in the heart. 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.
