Ambulatory blood pressure

Ambulatory Blood Pressure is your blood pressure being taken by a monitor at regular intervals over 24 hour period as you move around in your daily normal life.


This test is not covered by OHIP.

What is it?

An ambulatory blood pressure monitor is a portable blood pressure recording device. It is used to record blood pressure readings at specified times during a 24-hour period. The monitor consists of an arm cuff attached by a flexible rubber tube to a lightweight monitor. The monitor sits in a pouch secured to a waist belt or shoulder strap.

Why is it done?

To assess patients whose blood pressure tends to increase in the doctor’s office (white coat syndrome).

To evaluate extent of hypertension (high blood pressure) or hypotension (low blood pressure).

To monitor the effectiveness of blood pressure medication.

How long does it take?

24 hours

How to prepare:

Wear loose clothing and a short-sleeved shirt, if possible, so that the blood pressure cuff and monitor can be worn easily. It is a good idea to take a bath or shower before coming to your appointment as you will not be able to do so while wearing the blood pressure monitor. Do not apply any body lotion or oil to your arms before the appointment, as this makes it difficult to place the blood pressure cuff.
