What is an exercise stress test?
This test can help your doctor diagnose heart disease. It shows how much your heart can manage before an abnormal rhythm starts or blood flow to your heart muscle drops.
There are different types, but the exercise stress test -- also known as an exercise electrocardiogram, treadmill test, graded exercise test, or stress EKG -- is used most often. It lets your doctor know how your heart responds to being pushed. You’ll walk on a treadmill or pedal a stationary bike. It’ll get more difficult as you go. The doctor will track your electrocardiogram, heart rate, and blood pressure throughout.
