Holter Monitoring in Children
What is Holter monitoring?
Holter monitoring is a way to continuously check the electrical activity of the heart. Your child will wear a small device called a Holter monitor for at least 24 to 48 hours. The device constantly checks your child's heart during this time. This is different from electrocardiography (ECG). ECG checks the heart for only a few minutes.
Your child's regular healthcare provider will likely refer you to a pediatric cardiologist for this test. This is a doctor with special training to treat heart problems in children.
Why might my child need Holter monitoring?
Some reasons for your child's Holter monitoring are:
- Chest pain
- Other signs and symptoms that may be from a heart problem. These include tiredness, shortness of breath, dizziness, or fainting.
- Irregular heartbeats
- Abnormal ECG

What happens during Holter monitoring?
Holter monitoring is done as follows:
- The healthcare provider places small plastic patches (electrodes) on your child's chest. Then he or she attaches the electrodes to the monitor with lead wires.
- The monitor is small and portable. It may be worn over the shoulder, in a special pouch, or clipped to a belt or pocket.
- You will be given instructions on:
- How to keep the electrodes attached to your child's skin
- How to check the monitor for problems
- When to call the healthcare provider’s office for help
- How to keep a record with the date and time of day of any changes in activity and symptoms
- What to avoid
- Once your child has been hooked up to the monitor and you have been given instructions, he or she will go back to his or her usual activities.
What happens after Holter monitoring?
Once the monitoring is complete, you will remove the electrodes and monitor from your child. Or you and your child will return to the healthcare provider’s office. The provider will look at the information from the monitor.
Depending on the results of the monitoring, your child’s provider may order other tests.
