What Is Holter Monitoring?
When Using a Monitor
Stay away from electric blankets, magnets, metal detectors, and high-voltage areas such as power lines. They may affect the recording. |
Holter monitoring is a painless way to record your heartbeat away from the doctor’s office. It is a small electrocardiogram (ECG) that you carry with you. Holter monitoring records your heartbeat for your doctor to review at a later time. You can receive your heart monitor in a hospital, test center, or doctor’s office.
Your Holter Monitor
When you receive a Holter monitor, small, painless pads (electrodes) are put on your chest. These connect to the lightweight unit, which attaches to a belt or shoulder strap. You need to keep the device on for at least 24 hours and complete a diary. While wearing the monitor, follow these tips:
- Try to sleep on your back.
- Do not take a shower. A sponge bath is okay.
- Follow your normal routine. Do not avoid stress, work, or exercise.
If an electrode falls off or the unit makes noise, call to see what you should do.
Holter Monitor Diary
- Write in the time of day for each entry you make.
- Note each change in activity, including when you take medicine.
- Note any symptoms you feel.
