An exercise stress ECG is used to measure the effect of exercise on your heart.
The technician will place electrodes on your chest. These patches are attached to an ECG monitor that follows the electrical activity of your heart during the test.
In the presence of a cardiologist, you will walk on a treadmill, slowly with the speed and incline increasing every 3 minutes to a level you are comfortable and capable of exercising at, similar to walking fast or jogging up a hill.
While you exercise, the activity of your heart is measured with an electrocardiogram (ECG). Your blood pressure readings are also taken.
