A stress test, sometimes called a treadmill test or exercise test, helps your doctor find out how well your heart handles its workload. As your body works harder during the test, it requires more fuel and your heart has to pump more blood. The test can show if there’s a lack of blood supply through the arteries that go to the heart.
The exercise stress test – also called a stress test, exercise electrocardiogram, treadmill test, graded exercise test, or stress ECG – is used to provide information about how the heart responds to exertion. It involves walking on a treadmill at increasing levels of difficulty, while your electrocardiogram, heart rate, and blood pressure are monitored.
