A heart murmur is an audible-vibrational whooshing, humming, rasping, or swishing sound due to turbulent blood flow. A heart murmur is different from a typical heart sound. If a doctor hears a sound that is concerning for an atypical heart murmur, they will order additional testing.
What does heart murmur sound like?
Heart murmurs are sounds — such as whooshing or swishing — made by rapid, choppy (turbulent) blood flow through the heart. The sounds can be heard with a device called a stethoscope. A typical heartbeat makes two sounds like "lubb-dupp" (sometimes described as "lub-DUP") when the heart valves are closing.
What does a heart murmur indicate?
A murmur means blood is flowing abnormally across your heart valves. A murmur may mean there's a problem with your heart. But heart murmurs are also present in healthy people who don't have a heart problem (called “innocent” heart murmurs).
