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

What happens during the stress 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 days
