Noninvasive Testing
Nuclear Stress Test
This test involves having several small pads called electrodes placed on the
chest. These pads will be connected to an electrocardiograph (ECG) monitor so
that your heart rate and rhythm can be observed throughout the stress portion of
the test. The reason for doing the test is to see the blood flow of the heart
and how well the heart is functioning. An IV (intravenous line) will be placed
in your arm. This IV line will be used to inject a nuclear isotope into your
blood stream during the test. This nuclear isotope will help to image your heart
with the aid of a special camera. You will have two sets of pictures taken. One
while your heart is at rest and one after your heart has been stressed. With the
information obtained from this test your doctor can determine proper diagnosis
and course of treatment.
In case you are unable to walk on the treadmill
your doctor may order a pharmacological stress test. You will receive a drug
that will help your heart simulate the effects of exercise.
If you are having a stress test, wear flat,
comfortable shoes (no bedroom slippers) and loose, lightweight shorts or
sweatpants. Do not have anything to eat or drink for 8 hours prior to your
appointment time. You should not have any caffeine for 24-48 hours before your
test. Be sure to bring all your medications in their original container with
you to your appointment. Also be sure and ask your doctor about your
medications and whether or not they may interfere with the test.
Regular Stress Test
This test involves having several small pads called electrodes placed on the
chest. These pads will be connected to an electrocardiograph (ECG) monitor so
that your heart rate and rhythm can be observed throughout the stress test. You
will then be asked to walk on a treadmill which will move slowly in the
beginning and gradually increase in speed and elevation as the test goes on. As
you exercise longer and harder your heart and blood pressure will be closely
observed for the response that occurs.
If you are having a stress test, wear flat,
comfortable shoes (no bedroom slippers) and loose, lightweight shorts or
sweatpants. Do not have anything to eat or drink for 4 hours prior to your
appointment time. Be sure to ask your doctor about your medications and whether
or not they may interfere with the test.
When you arrive, please have the following:
- Picture identification.
- All health insurance cards and numbers.
- All medications in their original container.
