Electrocardiography (ECG) is a simple, fast test to check the electrical activity of your child's heart as blood moves through it. Abnormal ECG results may mean there is a problem with your child's heart.
An exercise ECG checks the electrical activity during exercise on a treadmill or stationary bike. This test is seldom done on young children. But it may be very useful in teens and young adults.
The test is done in a healthcare provider's office, hospital, or another place. The equipment used includes an ECG machine, electrodes, and wires. The wires connect the electrodes to the ECG machine. A blood pressure cuff is also used to check your child's blood pressure during exercise. Your child will exercise on a treadmill or stationary bike.
Exercise ECG testing usually follows these steps:
The test will take about an hour, including check-in, preparation, and the test.
Your child may feel a little tired or sore after the test, particularly if he or she is not used to exercising. Otherwise, your child should feel normal after the test.
Depending on the results of the exercise ECG, your child’s healthcare provider may order more tests.
