Available Pediatric Cardiology Tests

These standard pediatric cardiac tests are offered right on-site at
our office:
  • Electrocardiogram (also called an “EKG” or “ECG”): This test measures the heart’s electrical activity and is completely painless. A series of electrodes (small metal 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).
  • Echocardiography (or “echo,” for short): This is a specialized form of ultrasound that builds a detailed picture of your child’s heart (an “echocardiogram”) using sound waves. Our echocardiogram room was specially designed to be colorful and comfortable for kids. Your child can even select a video to watch while we perform the test.

Other Pediatric Heart Tests

Access to a kids-only Cardio-Pulmonary Testing Lab gives us the added ability to perform a cardiopulmonary exercise assessment (also called an "exercise test" or a "stress test") if your child needs it.

In an exercise test, kids are attached to an EKG machine and their heart rate and rhythm are measured while exercising — for example, riding a stationary bicycle or walking on a treadmill under supervision. If your child has or might have a heart problem or has undergone heart surgery, this test will help you to know which kinds of physical activities are OK and which ones aren’t. It can also pick up abnormalities in the heart’s rhythm that aren’t obvious during rest.

If your child needs additional tests, hospitalization or surgery, we’ll refer you to our Nemours Cardiac Center in Florida.
