SYSTEM 8000是一种用于产前胎儿心率（FHR）分析的计算机化系统，具有在线交互功能，以确保高质量的记录，并最大限度地减少获得必要信息（基于胎动和分娩力计读数以及FHR）所需的时间。 该设备包括一台带硬盘的个人电脑，与胎儿监护仪相连。 软件是用C写的。 对系统计算的大多数功能和参数给出了广泛的定义，例如记录质量、子宫收缩峰值、基础心率、变化、减速和加速。 它们的存在自然地影响在例如20-30分钟内计算的平均FHR变化。 但是，随着这些发作的幅度随着生长迟缓和低氧血症而减弱，变异的测量值下降。 实际上，在评估胎心率变异性时，观察者间和观察者内的变异性最大。 然而，变异的减少是胎儿恶化的最可靠指标。 该系统测量FHR的变化准确和可重复性，以及胎动。 在天气显示这两个同样重要的胎儿变量给予其应有的突出。 观察进行性呼吸功能不全的胎儿基础胎心率变化是多么罕见，以及极端心动过速（基础心率> 170/min）如何倾向于反映其他胎儿问题，如感染或母体发热，这是很有趣的。
SYSTEM 8000 is a computerized system for antenatal fetal heart rate (FHR) analysis, with interaction online to ensure good quality recording and to minimize the time required to obtain the necessary information (based on fetal movements and tocodynamometer readings as well as FHR). The equipment consists of a Personal Computer with hard disk, interfaced to a fetal monitor. Software is written in C. An extensive definition is given on most of the functions and parameters as calculated by the system, e.g. record quality, uterine contraction peaks, basal heart rate, variation, decelerations and accelerations.System 8000 is designed to take account of the episodic changes in FHR and fetal movements characteristic of sleep states. Their presence naturally affects the mean FHR variation calculated over, say 20-30 mins. But, as the amplitude of these episodes is attenuated in association with growth retardation and hypoxaemia, the measurements of variation decline. In practice inter- and intra-observer variation is greatest in assessing FHR variation. Yet a decrease in variation is the most reliable index of fetal deterioration. The system measures FHR variation accurately and reproducibly, as well as fetal movements. In the synoptic display these two equally important fetal variables are given their rightful prominence. It has been interesting to observe how rarely the basal FHR changes in fetuses suffering progressive respiratory insufficiency, and how extreme tachycardia (a basal rate > 170/min) tends to reflect other fetal problems such as infection or maternal pyrexia.
