一种应时的电子计算机系统已用于分娩期间胎儿心电图的连续监护。来自头皮电极的信号经扩大、滤波并通过界面系统而到达计算机。依据分娩期正常胎儿精确界限的严格标准,从110例的研究中选择出37例,找出了有关胎儿心电图的平均值及其各种参数范围。由于拥有大量的资料,产生了显示分娩期侧式分娩时胎儿的心电图长、短期 A timely electronic computer system has been used for continuous monitoring of fetal electrocardiograms during childbirth. The signal from the scalp electrode is amplified, filtered and passed through the interface system to the computer. Based on the strict criteria for the precise limits of normal fetuses during labor, 37 patients were selected from 110 studies to find out the average value of the fetal ECG and its various parameters. Owing to a large amount of data, a long and short term electrocardiogram showing the fetus at the time of delivery was shown
