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.
Following this big effort, ventricular muscle cells relax and get ready for the next contraction. During this period, little or no electricity is flowing, so the ST segment is even with the baseline or sometimes slightly above it. The faster the heart is beating during an ECG, the shorter all of the waves become. The shape and direction of the ST segment are far more important than its length.
