    Author(s): Kazuo MaedaKazuo Maeda

    Abstract Aims: The actocardiogram (ACG), which recorded fetal heart rate (FHR) and movements, was quantitatively analyzed, due to its advantage to the FHR patterns diagnosis, to recognize the effect of fetal movement on FHR, to solve controversial FHR problems, to correctly evaluate fetal disorders, and to evaluate the loss of variability and acceleration. Methods: FHR changes were diagnosed by the FHR score, fetal movements were evaluated by 4 ACG parameters, fetal behavior and abnormal FHR were quantitatively determined, physiologic sinusoidal FHR was diagnosed by the ACG and FHR frequency analysis, the developing mechanism of FHR acceleration and variability were studied to diagnose the brain damage in the loss of FHR variability. 1.3 Results: The FHR score, neural network analysis and A/B ratio predicted short and long term outcomes in the 1st stage of labor or even in pregnancy. ..
