How does my doctor diagnose a heart murmur?
Usually, your doctor will find a murmur during a regular exam. When listening to your heart with a stethoscope, your doctor may hear a "whooshing" sound. This sound is called a murmur.
If your doctor suspects a problem, he or she may choose to refer your child to a pediatric cardiologist. This is a kind of doctor who has spent extra time learning about children's hearts. The cardiologist will examine your child and might do tests to find out if there is a problem. These tests include chest X-ray, electrocardiogram (EKG or ECG) or echocardiogram (sometimes called an "echo").
