The present studies were designed and performed to investigate different aspects of the reliability of EFM, including the effects of methodologic changes in the assessment of tracings on the reliability of EFM. Analysis of FHR patterns. The validity and the relatively low reproducibility of FHR assessment may be improved by standardization. To that purpose it was tried to develop a classification of FHR patterns consisting of different sets of criteria applicable to each FHR pattern, exactly defined, mutually exclusive and complementary. For comparibility, such a classification should resemble classifications that were used previously but lacked these characteristics • The latter classifications were used in completely visual analyses. It was tried to answer the question as to whether the use of the developed classification and the use of a template in visual analysis further reduce observer variation. Finally it was investigated whether the validity of EFM might be improved by using a standardized duration of the tracings of such a length that unexpected fetal acidosis will probably not occur before the end of the tracing (<120 min.), and the influence of biologic variability of the FHR on the analysis will be limited
