Exercise Stress Test

What is the test?

The exercise stress test, also known as the treadmill test or exercise tolerance test, indicates whether your heart gets enough blood flow and oxygen when it's working its hardest, such as during exercise. Often, stress tests are given to people with chest pain or other symptoms who appear to have coronary artery disease, based on a medical exam and electrocardiogram (EKG). In addition, these tests are sometimes used for other purposes, from assessing the effectiveness of heart disease treatment to gauging the safety of a proposed exercise program.

Your heart health can be examined during and after exercise either by using an EKG or an echocardiogram (ultrasound of the heart). When this test uses an echocardiogram it is called an "exercise echo."
