Treadmill Test (Exercise Stress Test)

What is a Treadmill Test?

A treadmill test, also called an exercise stress test, helps us understand how your child’s heart functions during physical activity. The test begins with gentle walking and gradually increases in speed and incline every 1.5 minutes. This allows our cardiologists to see how the heart responds to stress.

The test is always supervised by a pediatric cardiologist and a cardiology technician, who remain in the room throughout. The cardiologist will stop the test once enough information is collected, or if any significant changes appear on the ECG tracing. Your child can also ask to stop the test at any time if they feel tired, dizzy, or experience chest pain.

What to Expect During the Procedure

Preparation

  • A technician will place small stickers (electrodes) on your child’s chest.

  • These electrodes are connected to clips and cables that monitor heart activity.

  • Oxygen levels are checked using a small finger clip.

  • Blood pressure readings are taken before and after the test.

The Test

  • Once prepared, your child will begin walking on the treadmill.

  • The treadmill gradually increases in speed and incline.

  • Comfortable clothing and running shoes are required.

  • Parents are encouraged to stay in the room for support.

After the Test

  • The cardiologist reviews the ECG and other measurements.

  • Results are used to assess how your child’s heart responds to exercise.
