What is a holter monitor?

A Holter monitor is a battery-operated portable device that measures and records your heart’s electrical activity (ECG) continuously for 24 hours. The monitor is attached to your skin with 3 sticky dots (or ECG electrodes). It is smaller than a mobile phone, and can be worn underneath your clothing. The holter monitor will record your heartbeat for the entire time it is worn.

 

Why should I have a Holter Monitor?

You may need a holter monitor if your doctor thinks there could be a problem with your heart rate or rhythm.

You might have symptoms such as:

  • Fainting
  • Dizziness
  • Shortness of breath
  • Chest pain
  • Irregular heartbeat (arrhythmia)

 

How do I prepare for the holter monitor?

It is a good idea to shower before your appointment to have your holter monitor fitted, as you will not be able to shower, or get the device wet once the monitor is attached to you.

 

 

What happens during a Holter Monitor?

When you arrive to have your monitor fitted, you will be asked to remove your clothes from the waist up. Ladies can keep their bra on.

Your skin will be prepared using a small alcohol swab, we will then use a some rough sandpaper to make sure we have a good contact with the ECG dots.

You will be shown what to do with the device should you experience any symptoms while wearing the monitor.

Once the monitor is fitted, you can return to your normal daily activities.

You will wear it all day and night, and will only remove it when you return to the clinic.

When you return to the clinic the monitor will be removed and the information will be downloaded. Once the information has been analysed by a cardiologist, a report will be sent to your referring doctor to review and decide the next course of action.
