What Is Holter Monitoring?

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.
