WHAT
IS THE PURPOSE OF A MICROVOLT T-WAVE TEST? The T-Wave Test is a non-invasive
treadmill test which is used to identify patients at risk of
life-threatening heart rhythm disturbances that can lead to sudden cardiac
death.
WHO ADMINISTERS THIS TEST?
An exercise physiologist administers this test.
HOW LONG WILL THE TEST TAKE?
The total amount of time this test will take is approximately one hour.
HOW
SHOULD I PREPARE FOR MY T-WAVE TEST? - Do not have any caffeine
(even decaf!) 12 hours prior to the test!
- Please bring a list
of your current medications, including dosage and frequency. Take your
medications at your usual time, unless your physician has indicated
otherwise. You may take your medication with juice, milk or a piece of
toast if necessary.
- You may have water or juice before your
test, but you should abstain from solid foods for at least two (2)
hours prior to your test. If you are a diabetic, please follow your normal
daily diet regimen.
- Please wear comfortable clothes and shoes
for your test. Slacks or shorts are preferred and shoes should be
appropriate for brisk exercise on a treadmill or a bicycle.
WHAT WILL I EXPERIENCE DURING
THE TEST?
- Prior to the test you will be asked to complete a personal history
questionnaire. This questionnaire must be updated each time you have a
test. You will also be asked to read and sign a consent form. This
form provides information regarding the benefits and risks of the test. Please do not hesitate to ask any questions that you may have.
- Your skin will be mildly rubbed in
preparation for the test. Several electrodes will then be placed on your
chest. These electrodes will be connected to a monitor so that your heart
rate and rhythm can be watched closely throughout the test.
- You will exercise by walking on a treadmill or pedaling a stationary
cycle. Both modes of exercise will start out slowly and then gradually
increase in speed and / or resistance. Your heart rate and blood pressure
will gradually rise. This is normal and both will be monitored along with
your EKG.
- You will be
encouraged to continually exercise throughout the exam. If you
experience any unusual symptoms at any time (such as chest pain, shortness
of breath or lightheadedness) immediately tell the exercise physiologist
monitoring the test. Adjustments will be made to the exercise test,
depending on your symptoms, blood pressure or degree of fatigue. You will be monitored after the test until your heart rate,
blood pressure and EKG return to resting levels.
