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.
- Don’t take a shower. A sponge bath is okay.
- Follow your normal routine. Don’t avoid stress, work, or exercise.
- If an electrode falls off or the unit makes noise, call to see what you should do.
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.
