Treadmill (exercise) stress test
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.
Variable, usually a total of 45 minutes (although very little of that time will be spent actually on the treadmill).
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.
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.
Yes, unless specifically advised not to do so by your doctor.
