A stress test can determine your risk of having heart disease. A doctor or trained technician performs the test.
The doctor will learn how much your heart can manage before an abnormal rhythm starts or blood flow to your heart muscle drops. There are different types of these.
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. Your electrocardiogram, heart rate, and blood pressure will be tracked throughout.
