The exercise stress test is a medical procedure that assesses how well your heart works as you exercise. It entails using a treadmill while attached to an electrocardiogram (ECG) device that measures the electrical activity of your heart.
The heart has to pump more blood during the exercise test because your body is working harder and using more oxygen. The test can reveal whether the blood arteries supplying the heart have less blood flow. The doctor can analyze your general level of fitness with the aid of an exercise stress test, which can also assist them to choose the best kind and intensity of exercise for you.

It’s important to discuss the results of your exercise stress test with your doctor to determine the next steps in your care plan.
