Background: Exercise electrocardiography is a long-standing method for the evaluation of coronary artery disease (CAD), and it remains the initial test for most patients who can exercise adequately with a baseline interpretable electrocardiogram. A normal Duke treadmill score is used to determine if a person is fit for work. A high score indicates that the person may respond well to additional treatments and should be monitored closely.
