The heart is a muscular organ that has four chambers. To absorb oxygen, it pumps blood to the lungs and to deliver oxygen to the body, it pumps oxygen-rich blood to the organs of the body. Four valves control the flow of blood from the chambers of the heart to the outside of the heart. Heartbeat sounds are the sound of valves closing. An extra sound in the baby's heart or a heart murmur is an extra sound that can be heard when the doctor listens with the examination phone. This extra sound is caused by the turbulent flow (eddy) of the blood. Heart murmur in children caused by disturbed blood flow can be normal or abnormal. In normal heart murmurs, the sound of blood flow is heard as it is normally pumped from the heart. This normal blood flow is called innocent murmur. More than 66% of all children and approximately 75% of all infants have a normal heart murmur. Abnormal blood flow indicates a problem or structural heart defect that requires further evaluation. Normal heart murmurs are usually louder when a child has a cold or fever, and usually (though not always) disappear by puberty. Related article What is the innocent whisper in the heart of children?
