Heart Murmurs and Children
 Heart murmurs in children are very common and are not usually cause for concern. But in some cases, additional symptoms might indicate that you should seek treatment for your child from a pediatric cardiologist.
Check out these FAQs about heart murmurs in kids to learn more.
What is a heart murmur?
A normal heart makes a specific sound when the heart valves close as the heart pushes blood through the body. A murmur is the sound of blood flow through the heart. Studies estimate that 75 percent of children will have a murmur at some time during their childhood.
How are murmurs diagnosed?
Murmurs are usually discovered during an exam with a stethoscope held at different areas on the chest. The murmur’s intensity is rated on a scale from 1 to 6 – from very soft to very loud.
Doctors will note the murmur’s location and characteristics, where it occurs in the heartbeat cycle and whether it changes as your child changes position.
What is an innocent murmur?
An innocent, or functional, murmur is most common, especially among preschool and school-age children. These are produced by a normal, healthy heart, and they can come and go throughout childhood. They don’t pose a health threat or require treatment. Your child will not need any long-term care or have any diet or activity restrictions.
When do murmurs become a concern?
Some murmurs indicate a heart abnormality. Structural, or congenital, heart defects, occur in about 1 of every 100 babies. Signs of these defects are often seen in newborns within the first few days of life. Others may not cause symptoms until later in childhood.
Some congenital heart defects occur with chromosomal disorders such as Down syndrome, or they may be related to certain gene abnormalities, or exposure to chemicals including alcohol or medications during pregnancy. Types of congenital heart defects include septal defects, which occur in the walls between the upper or lower chambers of the heart, valve abnormalities, and cardiomyopathy, or heart muscle disorders.
If a doctor suspects the murmur is caused by a heart problem, you will be referred to a pediatric cardiologist for further testing. These can include a chest X-ray, electrocardiogram or echocardiogram. If an underlying problem exists, a pediatric cardiologist will recommend treatment options including monitoring, medication and/or surgery.
When should I call a doctor?
Make an appointment with your pediatrician if your child experiences the following symptoms.
For newborns and infants:
- Rapid breathing
- Difficulty breathing
- Blueness in the lips
- Failure to thrive
For children and adolescents:
- Fatigue
- Difficulty exercising or doing physical activity
- Chest pain
Before your appointment, note your child’s symptoms, any family history of heart murmurs or other heart problems, any medications your child is taking and a list of questions you may have for your child’s doctor.
Keep in mind, however, that heart murmurs are fairly common, they are not a disease, and most turn out to be harmless.
