Treadmill (exercise) Stress Test

 
What it tells us
Stress testing is used usually to determine if there is a problem with blood supply to an area of the heart (coronary artery blockage).

Occasionally, this test is ordered for other reasons such as looking for heart rate, arrhythmias (irregular heartbeat), blood pressure or other responses to a higher heart load.
How long does it take?
Variable, usually a total of 45 minutes (although very little of that time will be spent actually on the treadmill).
What to expect
You will be connected to a special EKG machine and then asked to walk on a treadmill. The speed of the treadmill starts slow, and speeds up every 3 minutes. Very athletic people may end up running; however, the average person will stop during a fast walk.
How to prepare
Wear comfortable clothes you would exercise in. Sneakers are preferred; however comfortable walking shoes may also be acceptable. Women may be more comfortable wearing an exercise/sports bra or top.

You may have a light meal before the test; however caffeinated drinks (coffee, tea or caffeinated soda) should be avoided.
Do I take my medications that day?
Yes, unless specifically advised not to do so by your doctor.
