Available Pediatric Cardiac Diagnostic Tests at Nemours duPont Pediatrics, Bryn Mawr

We offer standard pediatric cardiac testing right on-site at our office:

  • Echocardiography (or “echo,” for short): This is our most frequently used pediatric heart imaging method. Echo is a completely safe and painless test that uses ultrasound (sound waves) to build a picture of your child’s heart.
  • Electrocardiogram (also called an “EKG” or “ECG”): This test measures the heart’s electrical activity and is completely painless. A series of electrodes (small sticky tabs) are simply fixed to your child’s skin in a few locations with tiny sticky papers. Then the information is transferred to a computer, where it’s stored and printed as a graph.
  • Holter monitor: This is an EKG that’s performed over a long period of time, usually 24 hours or more. Electrodes are connected to the chest and the wires are attached to a portable EKG recorder. Your child will be encouraged to continue normal daily activities, but must be careful to not get the electrodes wet (that means no swimming, showering or activities that cause a lot of sweating). There are two kinds of Holter monitoring: “continuous recording” (when the EKG is on throughout the entire monitoring period) and “event monitoring” (when data is recorded only when your child feels symptoms and then turns the Holter monitor on).
  • Ambulatory blood pressure monitors: In some cases, it’s important to measure a child’s blood pressure when participating in normal activities (in school, on the field, playing with friends, etc.) over a span of 24 hours. This monitor uses a small digital blood pressure machine that’s attached to a belt around your child’s body and is connected to a cuff around the upper arm. It’s small enough that kids can go about their normal daily lives and even sleep with it on.

Get an Early Start: Fetal Cardiac Testing

About two-thirds of children with critical heart disease are diagnosed while still developing (before birth) or soon after. Thanks to our highly skilled team and advanced technology at Nemours duPont Pediatrics, Bryn Mawr, most children — even newborns only hours old — who are born with a heart condition can be treated right away.

If you’re pregnant, your family obstetrician and/or perinatologist (a doctor who specializes in high-risk pregnancies) suspect your baby may have a heart condition, we’ll work together to see what’s going on inside your baby’s tiny ticker. As early as the 18th week of the pregnancy, we can perform fetal echocardiography (fetal “echo”) — an in-depth cardiac ultrasound study that allows us to view the structure, function and rhythm of a baby’s heart while still in the womb.

In cooperation with the Nemours Partners for Perinatal Management Program, we’ll help you understand your baby’s condition, coordinate consultations with one of our pediatric cardiologists, and plan for any necessary treatment at or soon after the birth.
