How are heart murmurs diagnosed?
You child’s doctor will evaluate your child’s murmur based on its pitch, character, location, loudness, and duration. Your pediatrician will decide if your child needs to be seen by a cardiologist. The most important thing early on is to diagnose the cause of the murmur.
