How the Test is Performed

The exercise stress test is a non-invasive test. Electrodes (small sticky patches) will be placed on
your child's chest, arms and legs. These electrodes will measure the electrical activity of the
heart. This is called and EKG or ECG.

Before the test begins, we will take baseline measurements of your child’s heart rate and blood
pressure. The blood pressure cuff squeezes the arm and may feel tight for a short time.

During the test, your child will walk on a treadmill and blood pressure readings will be taken
throughout. This will measure the heart's reaction to exercise.

The treadmill gets faster and steeper every 3 minutes. We will ask your child to go for as long as
they can, and will encourage them to push themselves. This will give us more information about
their heart. We will monitor your child for 10-15 minutes after exercising, or until their heart rate
returns to normal.

Your child’s cardiology care team may ask your child to wear a mask on their face that will
measure how much oxygen they are getting. This is another way to check how the heart is

Sometimes, a stress echocardiogram will also be done before and after the test. Your child’s
cardiology care team will let you know if an echocardiogram has been ordered.

Test Results
Your child’s cardiology care team or doctor will discuss the results with you in person, by
telephone, or by MyChart.

The results of this test will help your child’s care team know how their heart is working. It will
help them come up with a treatment plan that is best for your child.
