Exercise Stress Test
An exercise stress test is used to screen for the effects of exercise on your heart.
There will be a $50 missed appointment fee or if cancelled with less than 24 hour notice,

BEFORE YOU COME
There are a few things we would like you to do prior to your appointment:
​
-
Bring a current list of your medications (or better yet, bring them in their original bottles!)
-
Wear loose & comfortable clothing/shoes that are fit for exercise
-
Please refrain from smoking, or drinking beverages containing caffeine or alcohol for 2 hours prior to your appointment
-
Please arrive 10-15 minutes before your scheduled time to fill out paperwork (or better yet, print it from the 'More Information' section below, under 'Exercise Stress Test Forms' and bring a completed version with you!)
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.
A technologist will place 10 electrodes (small stickers) on your chest to monitor and record the electrical activity of your heart during the test. You will then walk on a treadmill. Roughly every 3 minutes, you will be asked to walk faster and on a slightly greater incline. It will feel like walking quickly or jogging up a slight hill. Along with the continuous monitoring of your heart rate and rhythm (electrocardiogram), blood pressure readings will also be taken at various intervals.
​
The test will continue until:
-
You reach a target heart rate
-
You develop chest pain or an excessive change in blood pressure
-
The electrocardiogram shows that your heart is not getting enough oxygen
-
You are too tired, or are experiencing other symptoms (shortness of breath, or leg pain) that is keeping you from continuing
