Treadmill Stress Test

A Stress Test is used to analyze your heart’s ability to respond to physical activity. As your heart pumps faster and harder during an exercise, a stress response is stimulated. It involves you to walk on a treadmill with an electrocardiogram (ECG) connected to your chest while your heart rhythm, blood pressure and breathing are monitored.


The level of mechanical stress is progressively increased by adjusting the difficulty (steepness of the slope) and speed.  Hence, problems within your heart may become unmasked by exposing the heart to the stress of exercise.

A doctor may recommend a Stress Test to:

  • dectect the likelihood of the narrowing of your heart arteries
  • diagnose a possible heart-related cause of symptoms such as chest pain, shortness of breath or lightheadedness
  • determine a safe level of exercise
  • check the effectiveness of procedures done to improve heart artery circulation
  • predict risk of dangerous heart-related conditions such as a heart attack


Depending on the results of the stress test, the doctor may recommend more tests such as a computer-tomography (CT) or catheter angiography.
