EXERCISE STRESS TEST 
 

What is an exercise stress test? 

• A stress test allows the doctor to learn how well your heart functions with activity 
• A stress test can detect heart problems that may not be present at rest  
• An electrocardiogram, also known as and ECG or EKG, records the electrical activity of your heart while you walk on a treadmill or pedal a stationary bicycle. 

Why has your doctor ordered a stress test? 

• Identify cause of chest pain, which can occur with blockages in blood flow to heart
• Monitor heart function of people with known heart disease
• Determine response to treatments and medications
• Look for abnormal heart rhythms that may occur with exercise
• Determine an exercise prescription for you

What information is obtained during a stress test? 

• Length of time that you were able to exercise
• Onset of symptoms, such as chest pain or pressure, jaw pain or arm pain, or extreme short of breath with exercise
• Response of heart rate and blood pressure to exercise

How do I prepare for a stress test? 

• Do not eat a heavy meal 2 hours prior to your test
• Avoid caffeine and nicotine 12 hours prior to your test
• Take your medications on the day of the test unless otherwise instructed
• Do not apply lotions or powders to the chest
• Avoid heavy activity on day of the test
• Wear loose, comfortable clothing and walking shoes

What happens during the test?

• You will be given an explanation of the test and asked to sign a consent form.
• Electrodes are placed on your chest and connected to an electrocardiogram (ECG) machine, which permits continuous monitoring of your heart rhythm.
• A nurse or exercise physiologist supervises your test.
  You will be shown how to use the treadmill or bicycle.
• Treadmill starts slowly at first and gradually increases in speed and incline.  A bicycle stress test may feel easy to pedal at first and then gets gradually harder.
• Your blood pressure is checked frequently, and your ECG is continually monitored.
• Report any symptoms, such as chest pain, shortness of breath, or dizziness
• Exercise as long as you can since that increases the accuracy of the test
• When the exercise portion is completed, your blood pressure and ECG will be monitored for several more minutes

When will I know the results of the stress test? 

• Final interpretation of the test results is completed by the cardiologist
• Your referring physician or family doctor receive a report within 3-5 days
