Electrocardiogram (EKG, ECG): About Your Child's Test
What is it?
An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your child's heart. An EKG translates the heart's electrical activity into line tracings on paper.
Why is this test done?
Your child may need this test to check his or her heart's electrical activity. The test also can check the health of your child's heart.
How do you prepare for the test?
- Tell your doctor about all the non-prescription and prescription medicines your child takes. Many medicines can change the results of this test.
- On the day of the test, don't use creams, lotions, powders, or baby oil on your child's skin.
- Bringing a toy, blanket, or doll might help your child feel more comfortable during the test.
How is the test done?
- Your child may have to remove certain jewellery.
- Your child may need to take off his or her top and may get a gown to wear.
- Your child will lie on a bed or table. Parts of your child's arms, legs, and chest will be cleaned and may be shaved.
- Small pads or patches (electrodes) will be placed, like stickers, on your child's skin on each arm and leg and on the chest. The electrodes are hooked to a machine that traces heart activity onto a paper. No electricity passes through your child's body from the machine. There's no danger of getting an electrical shock.
- During the test, your child will need to lie very still and breathe normally. Your child shouldn't talk during the test.
