Holter Monitor

A Holter monitor is a small device that records your heart beat and can be used to investigate palpitations. The small monitor is an electrocardiogram (ECG) that records your heartbeat nonstop throughout the 24 hour to 10 day period. Your doctor has ordered a Holter monitor because of some symptoms you are experiencing. The whole procedure is completely painless.


There is no specific preparation needed for initiating use of the monitor. It is helpful to wear a shirt or blouse that buttons down the front and is easy to remove. It should also be loose enough to fit over the electrodes and monitor.


You will wear a pocket-sized monitor with 5 pads (electrodes) applied to your chest. It's important that your skin is clean and dry. You will need to keep the device on for at least 24 hours (up to 10 days) and complete a diary. If you develop an attack of palpitation whilst you are wearing the monitor you will be advised to record the timing of such an event - the time should be easily visible on the front of the ECG monitor. While wearing the monitor, follow these tips:

  • Don't take a shower - a sponge bath is OK.
  • Follow your normal routine - don't avoid stress, work, or exercise.

It usually only takes a maximum 5 minutes to fit the device and a minute or less to remove it. We will normally ask you to remove the device yourself at a certain period of time after you have worn it. We will ask you to return it to us for further analysis and interpretation before a report can be sent to your doctor.
