FECG: fetal electrocardiogram; FHR: fetal heart rate; CI: confidence interval; BFHR: basal fetal heart rate; STV: short-term variation; DC: deceleration capacity; AC: acceleration capacity; LA: large acceleration; PEHV: proportion of episodes of high variation; PELV: proportion of episodes of low variation; ROC: receiver operating characteristics.
