This is a list of the most common symptoms that might indicate a heart problem in children.

In most cases, children with these symptoms don't have heart problems. For instance, some children naturally sweat more, and many children sweat while they sleep. Palpitations may be caused by caffeine. Dizziness may suggest that your child isn't drinking enough fluid.

However, if your child has any of these symptoms, it's important to tell your pediatrician or primary care doctor. He or she will listen to your child's heart and make a full medical evaluation, and then decide whether a referral to a pediatric cardiologist is appropriate.
