Stress Testing

What is a Stress Test . . .

A stress test records the heart’s response to exercise as an individual walks on a treadmill.

Why am I having this test . . .

In some cases, a stress test is part of a periodic physical examination. In other cases, it is helpful to diagnose blocked heart arteries or evaluate symptoms such as: chest pain, dizziness, fatigue, palpitations or shortness of breath.

Before the test ...

• Fast prior to test.


• Please consult your physician regarding medication instructions.


• Wear comfortable, loose fitting clothes, and walking shoes or sneakers. Women should avoid wearing underwire bras.


• You will need to sign a consent form before the test. Your doctor will explain the risks of the test.

During the test ...

Pads will be placed on your chest to monitor your heart rate. A cuff will be placed on your arm to monitor your blood pressure. You will walk on a treadmill which will gradually increase in speed and incline, usually every three minutes. Once your target heart rate is achieved, the test will conclude. If you experience any chest discomfort, dizziness, weakness, or fatigue, notify the doctor immediately.

The most common Nuclear Stress Tests are Myoview and Thallium. Upon registration, patients will go to the Emergency Department to have an IV tube inserted. Since the radiopharmaceutical is radioactive, it is extremely important to notify your doctor if you suspect that you are pregnant. A small dose of this material is given. Reactions are rare. A doctor and technician will be present at all times during this test.

For a Myoview Stress Nuclear Test, the radiopharmaceutical injection is given first, and then, resting films are taken in the X-ray Department . After the stress test is given, (description above), radiopharmaceutical may be injected again, and you will be taken to the X-ray Department for stress films.

For a Stress Thallium Test, the process is the same except in a different order. After the stress test is given, the radiopharmaceutical injection is given, and stress films are taken in the X-Ray Department. After a rest period, you will return to the X-Ray Department for resting films.

How long does it take?

There are two sets of pictures with the nuclear stress test. In-between the two sets there may be a 2 - 3 hour wait depending on scheduling. Please keep this in mind when scheduling your appointment.

After the test ...

You may go home and resume regular activities. Strenuous activity, however, should be avoided. If at any time you experience chest pain, dizziness, weakness or shortness of breath, call your doctor!
