Holter Monitoring

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
  • Stay away from electric blankets, magnets, metal detectors, and high-voltage areas such as power lines. They may affect the recording
  • 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
