    Exercise Electrocardiogram

    What Affects the Test

    You may not be able to have the test or the results may not be accurate if:

    • The electrodes are not securely attached to the skin.
    • You are not able to exercise hard enough during the test.
    • You take certain medicines, such as digoxin, phenothiazines, and some antiarrhythmic medicines.
    • You have a low potassium level.
    • You smoke or eat a heavy meal before the test.

    What To Think About

    An exercise EKG is not always accurate. The test results from an exercise EKG are always evaluated along with other information, such as your symptoms and other risk factors.
