• Holter monitoring is a continuous, 24-hour electrocardiographic (ECG) recording of the heart’s rhythm.
• Electrodes are placed on the chest area with the leads attached to a
  small recorder.
• You will keep a 24-hour diary to record daily activities and any symptoms you might experience.
• It will take 15 minutes to have the monitor put on.
• You will return the next day to have the monitor removed.
• This test must be ordered by a doctor.

Why is holter monitoring done?

• This test will help the doctor evaluate the type and amount of irregular heartbeats during regular activities, exercise and sleep.

What can be expected after the monitor is put on?

• Once the monitor is in place, do not touch or adjust the electrodes or the monitor.
• Do not get the electrodes or monitor wet.
• Do not have xrays taken while wearing the Holter monitor.
• Avoid using an electric blanket, heating pad or water bed while wearing
  the monitor.
