[Automatic analyses of rapid fluctuations of basal fetal heart rate during delivery. Verification of parameters].
The authors using an electronic calculator have measured 3 parameters, which allowed them to carry out quantitative evaluations of rapid variations in basal fetal cardiac rhythms (fluctuation) of 29 samples of fetal heart rate obtained during labour. The three parameters are: 1. Mean variation by intervals. 2. Values for differences in intervals approaching zero. 3. Zero changes in the derived curve. Each of these parameters was compared with the values of fluctuations which were obtained by visual analysis quantified on the same samples of tracings. The results of these coefficients of correlation show that the chosen parameters enable quantitative values for these fluctuations to be obtained.
