To study the diagnostic values of intrapartum fetal electrocardiography (FECG) and cardiotocography (CTG), 68 patients in labor were monitored at random. One-min Apgar score was chosen as the gold standard. The specificity (87.1%) and accuracy (86.8%) of FECG were found better than those of CTG (54.5% and 57.4% respectively). Fetal hypoxia and acidosis was firstly manifested by shortened P-R interval, FHR deceleration and increase in the T wave amplitude. It suggested that FECG can be a reliable diagnostic method following CTG screening.
为研究产时胎儿心电图（FECG）和胎心监护（CTG）的诊断价值，对68例分娩期患者进行了随机监测。选取1分钟阿氏评分作为金标准。结果发现FECG的特异性（87.1%）和准确性（86.8%）优于CTG（分别为54.5%和57.4%）。胎儿缺氧和酸中毒首先表现为P-R间期缩短、胎心率减速和T波振幅增加。这表明FECG可作为CTG筛查后的可靠诊断方法。
