24 Hour Holter Monitoring

A Holter monitor is a small, battery-powered device that measures your heart’s rate (speed) and rhythm. Your doctor may ask you to wear one if they need more information than a standard 30 second ECG provides. 

Holter monitors can help diagnose the cause of palpitations, light headedness or fainting spells. They are also used to help guide the dosing of medications for heart rhythm issues like Atrial Fibrillation or Atrial Flutter

What to expect

A Holter monitor is slightly larger than a deck of playing cards. Several leads, or wires, are attached to the monitor and are connected to electrodes (stickers) that are placed on the skin of your chest. The electrodes capture your heart’s electrical activity which is recorded by the Holter monitor. You wear a small pouch around your neck that holds the monitor itself. 


You’ll get instructions that explain how to take care of your monitor and what not to do while you’re wearing it (such as bathing, showering, and swimming ). You’re encouraged to participate in your normal activities during the 24-hour Holter test. You’ll be directed to record your activities in a notebook which will help your doctor determine if changes in heart activity are related to your behaviors and movements.

Wearing the Holter monitor itself has no risks involved. However, the tape or adhesives that attach the electrodes to your skin can cause mild skin irritation in some people. Make sure to tell the technician that attaches your monitor if you’re allergic to any tapes or adhesives.


Holter monitors can be booked by appointment by calling (250) 762-9211

Note: A 'borrowing' or loan agreement will be required in order to provide the Holter monitor to the patient for 24 hours.  This ensures the equipment is returned safely and on time for the next patient. The agreement can be reviewed here:
