When a heart valve isn't closing properly.
A doctor can hear a swishing sound when he listens with his stethoscope.
When the heart beats, normally it makes two sounds, "lubb" when the valves between the atria and ventricles close, and "dupp" or "dub" when the valves between the ventricles and the major arteries close. A heart murmur is a series of vibratory sounds made by turbulent blood flow through the heart. The sounds are longer than normal heart sounds and can be heard between the normal sounds of the heartbeat.
