Holter Monitor

What Is Holter Monitoring?

Holter monitoring is a painless way to record your heartbeat away from the Northside Gwinnett Medical Center. It is a small electrocardiogram (EKG) that you carry with you. Holter monitoring allows your doctor to review your heartbeat at a later time. This equipment helps doctors determine if you are at risk for heart disease or cardiac arrhythmias.

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 of your heart activity. 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 Northside Gwinnett Medical Center for instruction.

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.
