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 sound made by turbulent blood flow within the heart. Your doctor hears this sound with a stethoscope. A murmur can occur in a normal heart. Or it may indicate some problem within the heart. Most often, the turbulence is normal. And the sound is called a benign flow murmur. It happens when blood flows faster through the heart, for example in a person who is anxious, has just finished exercising, has a high fever or has severe anemia. About 10% of adults and 30% of children (most between the ages of 3 and 7) have a harmless murmur produced by a normal heart. This type of murmur is also called an innocent murmur.
