BACKGROUND Recent reports critical of the performance of heart rate-adjusted indexes of ST depression during exercise electrocardiography have used J-point rather than ST segment measurements. However, no standard exists for the optimal time after the J-point at which to measure ST segment deviation.
Although a diagnosis of ST-segment elevation myocardial infarction (STEMI) that mandates emergency reperfusion therapy requires ST-segment elevation greater than 1 mm in at least two contiguous leads, 3 any ST-segment depression or elevation (â¥ 0.5 mm, using the usual standard of 1.0 mV = 10 mm) may be abnormal, particularly when the clinical context or the shape of the ST segment suggests ischemia, or when other ischemic signs such as T-wave abnormalities, Q waves, or reciprocal ST ...
