Treadmill Stress Test

A treadmill stress test is an electrocardiogram (ECG) used to assess the cardiovascular condition during physical effort. While you are walking on a treadmill, your heart’s response to exercise is recorded.

The stress test is used to detect cardiac problems or to assess a medical condition, for example:

  • Identify the cause of chest pain
  • Diagnose or assess the progression of a cardiovascular disease
  • Detect conditions relating to irregular heartbeat, very fast or slow heartbeats, palpitations, dizziness or excessive fatigue
  • Determine a safe intensity level and frequency of physical activity a patient may undertake.

The treadmill stress test is provided by the Cardiology Clinic.

How to access our services?

  • You must have a referral from your physician to pass the treadmill stress test.

Preparation and procedure

  • Patients with mobility issues should not be referred for this test.
  • The test is a demanding physical effort.
  • Do not eat during the two hours preceding the test.
  • Do not smoke for at least one hour before the test.
  • Your doctor may ask you to stop taking one or more of your medications before the test.
  • Electrodes are attached to your chest. The technologist may shave the skin or use a light sandpaper to ensure the electrodes adhere to your skin. Ensure your skin is clean, dry and free of any oils or creams.
  • The electrodes are connected to a machine that records the electrical activity of the heart.
  • The test is done while walking on a treadmill.
  • You will start to walk slowly, and then the speed of the treadmill will increase gradually. Your heart rate, breathing and blood pressure are closely monitored throughout the test.
  • The test continues until your heart beats fast and you reach your peak capacity, according to your age and medical condition.
  • You must inform the technologist if you feel any pain or discomfort.
  • The test lasts from 15 to 30 minutes.
