Heart murmurs are common in children, and are most often a normal part of their growth. At some point, just about every child will have a heart murmur. A heart murmur usually doesn't mean that your child has a serious health issue. But in rare cases, a heart murmur can be a sign of a serious condition. That's why it's important for your child to see a cardiologist. A cardiologist can find out if your child's murmur is caused by a problem in his or her heart, or if it's nothing to worry about.

A cardiologist can find out if your child's murmur is caused by a problem in his or her heart, or if it's nothing to worry about.CausesThere are 2 kinds of heart murmurs in children. The first is known as an innocent heart murmur. It's also called a functional murmur. This is simply the normal sound of blood pumping through your child's heart. Innocent murmurs are very common in children. If your child has an innocent murmur, it shouldn't cause any problems or health concerns. The other type of murmur is a structural murmur. This type of murmur may be caused by a problem with a heart valve or a hole between the 2 pumping chambers of the heart. A baby can be born with a structural murmur because of defects in the heart that happened during pregnancy. This is called a congenital murmur. Murmurs can also show up in children as a result of diseases such as: Thyroid diseases. Rheumatic fever, which can happen when strep throat is untreated.

For this test, electrodes are placed on your child's skin to record the electrical activity of the heart.TreatmentIf your child has an innocent murmur, he or she won't need any treatment.
