How does a murmur sound?

A heart murmur is a sound caused by blood flow within the heart. Instead of ‘lub-dub’, the heartbeat may have an added sound like a hum, a whoosh or a rasp. The cause of the whooshing sound is the vibration of blood as it moves through the heart, which is normally undetectable by stethoscope.

Can murmurs go away?
