Every beat of the heart makes a sound discernible by medical equipment; this is the heart valves opening and closing. If a doctor with a stethoscope, or any other device, notes an interruption or irregularity when listening to a patient's heart, they will note this murmur. There are two types of heart murmurs: innocent and abnormal. They can be present from birth or develop over time.
Newborns or children may have an innocent heart murmur and a normal heart. This occurs when blood flows quicker than normal through the heart. Some people experience this type of heart murmur during exercise, pregnancy, or rapid growth spurts. Fever, anemia, or hyperthyroidism can also cause an innocent murmur. If it does not disappear on its own over time, then an innocent murmur can be a life-long condition, but is unlikely to result from or cause any health problems.
