A heart murmur is a continuous sound that is audible with a common stethoscope, produced when blood passes through particular areas of the heart. The heart has four chambers, two atria (singular = atrium) and two ventricles separated by a skeleton of cartilage that separates each chamber.
A heart murmur is a whooshing sound between the beats that a doctor hears through a stethoscope. The whoosh is just an extra noise that the blood makes as it flows through the heart. Doctors usually discover murmurs during regular checkups or when kids see the doctor because they're sick. Just like kids, murmurs have grades. Grade 1 is the softest-sounding murmur, and Grade 6 is the loudest.
