Other Information About Your Cardiac Stress Test
This test was ordered by your doctor so he or she could check the blood supply to your heart muscle and make sure your hearts arteries (or any bypasses or stents that you have had) are open and allowing good blood flow to your heart muscle.
The test consists of an exercise test and two sets of pictures of your heart.
The exercise test can be done by walking on a treadmill or administering a medication to mimic the effects of exercise on the heart.
The pictures will be taken before the exercise test and after the exercise test. The two sets of pictures will be compared by the doctor to determine if there are any problems with the blood supply to your heart muscle.
What will happen during the test?
You will be asked to change from the waist up into a gown so the electrodes can be placed on your chest to monitor your heart during the exercise test and during the imaging.
You will have an IV placed in your arm so we can inject the tracer for the pictures and any medication you may require for the test.
After the IV is in place, you will receive the first injection of the tracer so we can take the first set of pictures. The tracer is a very small amount of radioactive material. You will not feel any effect from it.
After the first injection, you will be escorted to Nuclear Medicine for the pictures. You will lie on your back with your arms over your head while the camera takes about 20 minutes of pictures of your heart from all angles. The camera will not affect pacemakers or any metal jewelry you may be wearing. You will be hooked up to an EKG machine for the second set of pictures so that we may get a motion picture of your heart. This is a normal part of the test and should cause you no concern.
After the first set of pictures, you will have the exercise test. You will receive a second injection of the tracer during the exercise test.
After the second injection, you will return to Nuclear Medicine for the second set of pictures. Your IV will be removed after the second set of pictures and the test is finished.
You may resume your normal diet and activity following the second set of pictures. The test results will generally be available to your doctor within 3-5 working days. Please tell us if you have an appointment before then.
Please feel free to call the Cardiologist if you have any questions. Thank you.
What is an Echocardiogram?
An echocardiogram or echo is a test that makes images of the heart with sound waves similar to radar. The test is harmless and is not painful. A specially trained ultrasound technician performs the test. Sound waves are sent out from a transducer and are bounced off the heart. These sound waves are picked up by the transducer and are then made into pictures of the heart.
Echo Test Results
These pictures of your heart are reviewed by a Valley Heart cardiologist who can identify any problems with the heart muscle or valves. The test usually takes approximately 30 minutes to complete. A written report is sent to your doctor. Your doctor may then recommend more tests or suggest therapy based on the results of this echo test.

What is a Stress Echocardiogram?
An echocardiogram or echo is a test that makes images of the heart with sound waves similar to sonar. The test is harmless and is not painful. A specially trained ultrasound technician performs the test. Sound waves are sent out from a transducer and are bounced off the heart. These sound waves are picked up by the transducer and are then made into pictures of the heart.
The stress or exercise portion usually involves walking on a treadmill at a slight incline until you have to stop. Sometime medications may be used to simulate exercise in patients who cannot walk well. An echocardiogram will be done to obtain images before and then immediately after treadmill exercise.
We measure your blood pressure, heart rate and monitor ECG during the entire study.

What will happen during this test?
You will be called back by our Nuclear Technologist and you will have an IV placed in your arm.
After the IV is in place the technologist will draw a sample of your blood. That blood will be mixed with a tracer and ½ hour after the blood was drawn it will be injected back into the arm. This will allow the technologist to take a series of pictures of your heart.
You will be asked to lie on your back with your arms over your head while the camera takes three sets of pictures of your heart from all angles.
