Holter Monitoring

What Is A Holter Monitor?

  • A holter monitor is a recording of your heart rate and rhythm over a 24 or 48 hour period.


How Is A Holter Monitor Performed?

  • You will be required to wear the monitor for roughly 24 hours or 48 hours (sometimes less) depending on what your GP prefers . The monitor is quite small and will either be placed in a small bag to hang around your neck or clipped onto your belt, and records your heart beat through leads which we place on the skin over chest.


What To Expect

  • You will not be able to shower while you are wearing the monitor and you are not to remove the monitor to shower during the 24 or 48 hour period.
  • It is recommended that you shower prior to your appointment.
  • While you are wearing the monitor you will be asked to do everything as per normal in your day to day life (other than showering).
  • You will be shown how to remove the monitor yourself and are required to return the monitor the following day at a time that will be given to you (this may be less than 24hours).



  • Once you return the monitor we can begin to analyse the recording. You won’t be given the results upon returning the monitor.
  • Once the monitor has been reported the results will be sent to your GP. It is generally a week turn around time from application to results being available at your GP or referring doctor’s practice.
  • If there is an urgent finding on your monitor, you will hear from your GP or referring doctor earlier.
  • If there is an urgent reason your monitor needs to be reported sooner, please notify the technician at your appointment.
  • If you cannot return the monitor the following day you must notify the receptionist at the time of booking, not once you’ve attended your appointment.
