Spiral scalp electrodes were applied in 30 cases of diagnosed intra-uterine death during labour to establish different patterns caused by maternal fetal conduction of the ECG. In 10 cases the signal was of high quality and in 20 cases the signal was of low quality, but nevertheless spurious fetal heart rate recordings were produced. The maternal heart rate is interpreted as apparent "fetal bradycardia" in all cases but 1. Maternal heart rate accelerations, most of them occurring during uterine contractions, were demonstrated in 12 cases and decelerations in 3 cases. Changes in beat-to-beat variation were, however, rare.
对30例分娩期间确诊为宫内死亡的病例应用螺旋头皮电极，以确定由母体 - 胎儿心电图传导引起的不同模式。10例信号质量高，20例信号质量低，但仍产生了假性胎儿心率记录。除1例病例外，所有病例中的母体心率均被解释为明显的“胎儿心动过缓”。12例显示母体心率加速，其中大多数发生在子宫收缩期间，3例显示减速。然而，逐搏变化的改变很少见。
