What is exercise EKG testing?

Exercise EKG testing is used to determine how your child’s heart responds to stress or exercise.

How does an exercise EKG test work?

  • Electrodes (small, plastic patches) are placed on your child's chest, arms and legs.
  • A blood pressure cuff monitors her blood pressure.
  • Your child begins to exercise on a treadmill or stationery bike.
  • The electrodes are connected to the EKG machine by lead wires, through which the electrical activity of your child's heart is measured, interpreted and printed out.
  • Resistance and speed are varied in order to give a harder or easier workout.
  • Your child will exercise until reaching a target heart rate or until unable to continue due to fatigue, shortness of breath, chest pain, irregular heart rhythms or other symptoms.

How should I prepare my child for exercise EKG testing?

The procedure will take about one hour, including check-in and preparation.

A hospital stay is not necessary unless your child's physician determines that your child's condition requires further observation or hospital admission.

Your child may feel a little tired or sore for a few hours after the procedure, particularly if he isn’t used to exercising. Otherwise, your child should feel normal within a few hours.

Boston Children’s is so much more than a hospital—it’s a community of researchers, clinicians, administrators, support staff, innovators, teachers, patients and families, all working together to make the impossible possible. ”
