Electrocardiogram (ECG)

What is an Electrocardiogram?

An electrocardiogram, or ECG, is a quick, safe, and painless test that records the electrical activity of your child’s heart. The ECG machine prints this activity onto special paper, creating a tracing that helps our cardiologists understand how the heart is working.

What to Expect During the Procedure

Stickers (Electrodes)

  • We place 10 small stickers (called electrodes) on your child’s chest, arms, and legs.

  • Each sticker is connected to the ECG machine with a clip and wire.

  • The stickers are gentle and easy to remove — they do not cause pain.

The Test

  • Once the electrodes are in place, the ECG begins.

  • The test itself takes only a few minutes.

  • The most important part is for your child to lie still while the recording is made.

  • We understand this can be challenging, so you are welcome to help distract your child with a favorite toy, a video on your phone, or any other comfort technique.

After the Test

  • When the recording is complete, the ECG machine prints out a tracing of your child’s heart rhythm.

  • One of our pediatric cardiologists will carefully review the results.
