BEFORE YOU COME

There is no special preparation for the test, however there are some things you may want to consider.

  1. You will not be able to shower or bathe while wearing the monitor (there are exceptions for 7, 14, 21, or 28 day monitoring) so you may want to do this prior to your appointment

  2. You will need to list your medications on a take-home worksheet, if you bring them in with you the technologist may be able to assist with this!

  3. Remember to tell the technologist if you are allergic to adhesives or if you generally have sensitive skin. We will make sure to set you up with our sensitive sensors.

WHEN YOU'RE HERE

This test is performed in Medical Centre 1

Suite 206, 430 The Boardwalk, Waterloo, ON

Please head to the CPS Registration Desk and we will direct you from there.

Electrodes (small conducting stickers) are placed on your chest and attached to a small battery-operated recording monitor, about the size of a cell phone. This test is painless, however some people require chest shaving so the electrodes can stick. 

How long will my appointment be?

15 mins

AFTER YOU LEAVE

You will carry the monitor on a clip attached to your waist while it records your heart's electrical activity. You will be asked to keep a diary of activities you do while wearing the monitor as well as any symptoms you may feel. After your scheduled time, you will remove the monitor yourself and return it to our office. 

There are some things to remember while wearing the device:

  1. The monitor cannot get wet. Do not bathe, shower, or swim while wearing the monitor.

  2. This device is sensitive and must not be tampered with. 

  3. While wearing the device, please avoid the following

    • Electric blankets​

    • High-voltage areas

    • Magnets

    • Metal detectors

 

Note: You may be asked to remove the device if you are going for other testing such as an MRI, CT scan, or X-ray​

Wearing a device and still having questions?

A holter monitor uses electrodes to measure the electrical activity of your heart.

 

Every time your heart beats, a wave of electrical activity travels through the heart. This wave is what forces the heart to pump blood to the rest of your body.

 

This electrical activity can be visualized through an electrocardiogram (ECG).
