Types of Cardiac Diagnostic Tests at Nemours duPont Pediatrics, Middletown

We offer pediatric cardiac diagnostic tests right on-site at our Nemours duPont Pediatrics, Middletown 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 sticky tabs) are simply fixed to your child’s skin in a few locations. 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 remote monitoring: “Holter monitor,” which is a 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 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.
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, Middletown, 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.
