The last 120 minutes of 394 intrapartum fetal heart rate (FHR) records of high technical quality were evaluated. Baseline FHR was estimated and oscillation frequency (OF) counted for each minute. There was a highly significant association between the baseline FHR and the number of oscillations/minute; an increase in baseline FHR of 10 beats/minute was associated with a fall of about one oscillation/minute. The highest mean OF (9.6 +/- 4.8 events/minute) was found in fetuses with an umbilical artery pH of between 7.20 and 7.25. The baseline FHR should be taken into account when assessing fetal condition.
对394份技术质量高的产时胎儿心率(FHR)记录的最后120分钟进行了评估。估计基线FHR并计算每分钟的振荡频率(OF)。基线FHR与每分钟振荡次数之间存在高度显著的关联;基线FHR每增加10次/分钟,振荡次数约减少1次/分钟。脐动脉pH值在7.20至7.25之间的胎儿的平均OF最高(9.6±4.8次/分钟)。评估胎儿状况时应考虑基线FHR。
