OBJECTIVES
To develop a computerized algorithm to quantify fetal heart rate (FHR) variability and compare it to perinatologists' interpretation of FHR variability.
METHODS
FHR variability was calculated using data from 30 women who had a fetal scalp electrode placed for a clinical indication, and compared to the assessment of FHR variability from four perinatologists who interpreted paper tracings of the same data. Inter-rater reliability was calculated and receiver-operator curve analysis was done.
RESULTS
Correlation between the computer algorithm's assessment of variability and the perinatologists' assessment (0.27-0.68) was similar to the inter-rater reliability between perinatologists (0.33-0.72).
CONCLUSIONS
A computer-based algorithm can assess FHR variability as well as expert clinicians.
目的
开发一种计算机算法来量化胎儿心率（FHR）变异性，并将其与围产医学专家对FHR变异性的解读进行比较。
方法
使用30名因临床指征放置胎儿头皮电极的女性的数据计算FHR变异性，并将其与四位解读相同数据纸质记录的围产医学专家对FHR变异性的评估进行比较。计算评分者间信度并进行受试者工作特征曲线分析。
结果
计算机算法对变异性的评估与围产医学专家的评估之间的相关性（0.27 - 0.68）与围产医学专家之间的评分者间信度（0.33 - 0.72）相似。
结论
基于计算机的算法评估FHR变异性的能力与专家临床医生相当。
