Exercise Stress Test

Also known as: Exercise stress test or cardiac stress test.

Duration:  About 15 minutes

The exercise stress test is a diagnostic test that checks the heart’s blood flow under “stress”/physical activity. While either walking on a treadmill or riding a stationary bicycle, the coronary arteries (the blood supply of the heart) are checked for any stenosis (narrowing) or blockages.

Uses:

• To diagnose coronary artery disease (CAD), valvular heart disease, heart failure, and others.
• To diagnose irregular heart rhythms (arrhythmias)
• To monitor the progress of certain treatments

How it is performed:

• The electrodes will be connected by lead wires to an EKG monitor and the electric activity of the heart is recorded as “waves.”
• An inflatable cuff is then placed around your arm to monitor your blood pressure and heart rate.
• You will be asked to either start walking slowly on a treadmill or ride a stationary bicycle.
• The treadmill/bike gets faster and steeper every few minutes until the target heart rate is reached or until you experience any symptoms like chest pain, dizziness, etc.
• In some situations, this test is combined with an echocardiogram or a nuclear cardiac stress test.

After the test:

• After the test is completed, you may be asked to stand still and then lie down for some time to check your heart’s recovery.
• Your cardiologist will discuss the results and the next steps of action.
• You can continue your daily activities.
• Ask your cardiologist if you have any questions or concerns.
