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.
The display system looks for the zero crossing of the sync pulse. Each half of the tri-level sync pulse is defined to be 44 samples (reference clock periods) wide, for a total sync pulse width of 88 samples. The rise time is defined to be four samples wide +/- 1.5 samples. This symmetry of design results in a net DC value of zero volts. This is one major advantage of tri-level sync.
