Holter Monitor

A Holter monitor is a machine that continuously records the heart's rhythms. The monitor is worn for 24 to 48 hours during normal activity.

Electrodes (small conducting patches) are stuck onto your chest. These are attached by wires to a small recording monitor. You carry the Holter monitor in a pocket or pouch worn around your neck or waist. The monitor runs on batteries. While you wear the monitor, it records your heart's electrical activity.

  • Keep a diary of what activities you do while wearing the monitor, and how you feel.
  • After 24 - 48 hours, you will return the monitor to your doctor's office
  • The doctor will look at the records and see if there have been any abnormal heart rhythms.

It is very important that you accurately record your symptoms and activities so the doctor can match them with your Holter monitor findings.
