Since the 1970s, intrapartum monitoring of the distressed foetus has been managed by continuous registration of the foetal heart rate, together with uterine activity (cardiotocogram; CTG). Use of CTG without additional foetal information leads to unnecessary interventions because of the high number of false-positive signals. Foetal blood sampling (FBS) is a solution to this problem, but is not always consistently carried out. Automated ST analysis of the foetal electrocardiogram (STAN method), combined with the CTG, may lead to reduction of metabolic acidosis, fewer interventions and fewer foetal blood samples. A disadvantage of application of the STAN method is that it is based on visual interpretation of the CTG, with large inter- and intraobserver variability. In spite of this shortcoming the method may be promising.
自20世纪70年代以来，对窘迫胎儿的产时监测一直通过持续记录胎儿心率以及子宫活动（胎心宫缩图；CTG）来进行。由于假阳性信号数量众多，在没有其他胎儿信息的情况下使用CTG会导致不必要的干预。胎儿血样采集（FBS）是解决这一问题的方法，但并非总能始终如一地实施。将胎儿心电图的自动ST分析（STAN方法）与CTG相结合，可能会减少代谢性酸中毒、减少干预措施并减少胎儿血样采集。应用STAN方法的一个缺点是它基于对CTG的视觉解读，观察者之间和观察者内部的变异性很大。尽管有这个缺点，该方法仍可能很有前景。
