Before Your Test

Knowing what to expect can help you stay relaxed.  Although you will exercise for just a short while, the entire test will take a few hours.  For best results, prepare for your test as directed.

· When you schedule the test, be sure to mention all the medications you take.  As if you should stop taking any of the  the day of the test.

· Before your test, stop smoking and avoid caffeine for as long as directed.

· Don’t’ eat or drink for 4 to 6 hours before the test.  Sips of water are okay.

· On the day of the test, dress for ease and comfort.  Wear a two-piece outfit, top and bottoms.  Be sure to wear walking shoes for the test.

During Your Test

You may be asked to change into a hospital gown for the test.  At some point, scanning pictures will be taken while you rest.  This may be done before you exercise. Or, you might have to return for resting scans later that day or the next.  During the actual test:

· You will be attached to EKG and blood pressure monitors.  An IV (intravenous) line will be started in your arm.

· You will exercise on a treadmill or stationary bike for a few minutres.  This increases the rate of blood flow to your heart muscle.

· Speak up when you cannot exercise for even 1 more minute.  At this point, the tracer is given to you through the IV.

· If you cannot exercise, special medications ca be used to increase heart rate.

· After you have received the tracer, you will be positioned on the scanning bed.

· You must lie very still for up to 30 minutes.  During this time, a scanning camera will be taking pictures.  The images will show where blood flows through your heart muscle.

Let the Technologist Know

· What medicines you take.

· If you have diabetes, knee or hip problems, arthritis, asthma, or chronic lung disease.

· If you have had a stroke or have vascular disease of the leg.

After Your Test

Before going home, ask when you may eat.  Also, find out when to resume taking any medications you were told to skip before the test.  If you need to return for testing scans, follow any instructions.  Most people can go back to their normal routine as soon as all parts of the test are finished.
