Excerpt

Exercise testing has served as the workhorse for the evaluation of ischemia for over half a century. Once electrocardiography was added to exercise testing,1 ECG changes occurring during ventricular repolarization, as manifested by ST depression, became the standard for an abnormal ECG response. Over time, test accuracy increased with the incorporation of the degree and time of onset of ST duration, duration of ST depression during recovery, exercise-induced symptoms, exercise duration, blood pressure response, heart rate recovery, and development of ventricular arrhythmia.2 …
