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.
ST-segment is a portion of ECG; its elevation indicates full thickness injury of heart muscle. Absence of ST-segment elevation in NSTEMI is understood to involve less than full thickness (partial thickness) damage of heart muscle. Therefore, NSTEMI is less severe type of heart attack compared to STEMI (ST-segment elevation myocardial infarction) in which full thickness damage of heart muscle develops.
