Patient Health InfoTreadmill Stress Test
A treadmill stress test uses an electrocardiogram and your blood pressure to evaluate the function of the heart during exercise or work. It allows your physician to detect cardiovascular disease and assess your cardiovascular fitness. There are several specific types of stress tests performed: thallium, dual isotope, cardiolite and persantine. Your physician will determine which test to administer.
Preparation
Do not eat or drink three or four hours before the test unless you are otherwise instructed. You will be asked to arrive a half hour before your scheduled test. Wear comfortable footwear and clothing appropriate for brisk exercise on a treadmill or bicycle. You will undress from the waist up and a hospital gown will be provided.
The Procedure
The procedure requires about an hour. Your actual exercise time will be three to 12 minutes.
Your chest will be shaved in small places, if necessary, and cleaned with a liquid abrasive and alcohol pads. Ten sponge pads called electrodes will be placed on your chest and connected to an EKG to continuously monitor your heartbeat and blood pressure.
You will exercise by walking on a treadmill, beginning slowly. The speed and incline of the treadmill will gradually increase.
If you feel chest or arm discomfort, shortness of breath or lightheadedness, tell your physician immediately. The length of the test will depend on your tolerance and symptoms. To improve the test''s accuracy, it is important to exercise as long as you are able.
Your blood pressure and heartbeat will be monitored for several minutes after you stop exercising. Then the electrodes will be removed and you will be free to go.
If you have questions, please ask your physician or the cardiovascular technicians who will be with you throughout the procedure. Your physician will discuss the test results with you. Your primary care physician will be notified of the results.
Following the Procedure
You may resume your normal activities and diet following the procedure. Please don't bathe or shower until you have recovered from the exercise.
