Our objectives were to increase the discrimination between fetal distress and fetal well-being, using fetal heart rate spectral analysis. Monitoring of the heart rate from 259 fetuses was done between 26 and 42 weeks, interpreted with classical criteria, and analysed with the spectral analysis method we developed. The fetal heart rate spectrum analysis performed on these recordings allow discrimination of fetal distress from the normal state using the energy value and frequency of the maximal energy in the high frequency band. We can conclude that the spectral analysis produces two significant parameters which could contribute to a multivariate approach to assessments of the physiological mechanisms of heart rate variability.
我们的目标是通过胎儿心率频谱分析，增强对胎儿窘迫和胎儿健康状况的区分能力。对259例胎儿在孕26至42周期间进行心率监测，采用经典标准进行解读，并运用我们开发的频谱分析方法进行分析。对这些记录进行的胎儿心率频谱分析，可利用高频带中的能量值和最大能量频率，将胎儿窘迫与正常状态区分开来。我们可以得出结论，频谱分析产生了两个重要参数，这可能有助于采用多变量方法评估心率变异性的生理机制。
