A cardiac stress test is used to monitor your heart rhythm, heart rate, and any changes to your heart rhythm as you exercise. This test will help your physician to diagnose coronary artery disease (CAD). Physicians order this test for the following reasons:

  • Strong family history of heart disease
  • High blood pressure or high cholesterol
  • Chest pain or heart palpitations
  • Follow up from a previous heart attack, angioplasty, bypass surgery, or stent insertion
  • For the Lifestyle Education and Experience Program (LEEP – before and after attending the program)
  • As a part of an annual check up
  • As part of your Chest Pain Clinic appointment

To have a cardiac stress test, your doctor needs to fill out a requisition form. Download cardiac stress test requisition form.

A cardiology technologist will perform the cardiac stress test. A physician will be present during the test to supervise and provide guidance to the technologist.

Before, During, and After Your Cardiac Stress Test

On the day of your cardiac stress test, please exclude caffeine products, alcohol, and smoking. Caffeine products include: coffee and tea (decaffeinated and caffeinated), chocolate, cocoa, soda, pop, and any medication or supplements that may have caffeine. It is recommended you stop using beta blockers 48 hours before your test. Check with your physician and/or pharmacist before stopping your medication.

You may have a light meal approximately two hours before your appointment. Bring loose-fitting, comfortable, short-sleeved exercise clothing (T-shirt and shorts or jogging pants), and rubber-soled shoes (running shoes). Do not wear a dress or skirt. Women must wear a bra for exercise. Please do not wear jewellery or perfume for your test. If you use an inhaler for asthma or other breathing problems, bring it to the test and let the technologist know. Bring a complete list of medication to your appointment.

Please arrive 30 minutes before your test to check in at the registration desk in the main lobby. Please bring your health card and your requisition (if your physician has provided you with one).

During Your Cardiac Stress Test

When you arrive for your cardiac stress test, we will explain the procedure to you.

You will be:

  • Hooked up to equipment to monitor your heart and blood pressure
  • Walking slowly on the treadmill. The speed will be increased slowly at certain intervals to increase your heart rate.
  • Continuously monitored by the technologist to record your heart rhythm and blood pressure throughout the test.
  • Finished the test when you reach your target heart rate.
  • Asked to lie down after the test so your blood pressure and heart rate can be recorded again.

Please allow one hour to complete your test.

After Your Cardiac Stress Test

There will be a five-minute rest period after the test where the technologist will continue to monitor your heart rate and blood pressure until they return to your baseline. After the test, you may return to your regular activities.
