The results of the nuclear stress test can show doctors if the heart is not working properly while you are resting, exercising, or both. If the test shows that blood flow is normal while you are resting but not normal while you are exercising, then doctors know that your blood flow to your heart is not adequate during times of stress.
During a standard stress test, your blood pressure will be checked. You also may be asked to breathe into a special tube during the test. This allows your doctor to see how well you're breathing and measure the gases that you breathe out. A standard stress test shows changes in your heart's electrical activity.
