[Accelerations of the fetal cardiac rhythm and fetal movements. Significance of their association recorded on the cardiotocogram by the Tococinon].

Recording all fetal movements on the cardiotocogram using tococinon showing forty minutes observations adds a new dimension to the old and new methods of monitoring the fetus. A group of 53 pregnancies without any risk was compared to a group of 37 pregnancies of high risk in which were also found sub-groups as designated by the aetiology and the severity of the fetal risk. Furthermore we have carried out a longterm study of 5 cases over six days. We propose a choice of the best parameters to be used according to their reliability, accuracy, sensitivity and predictability. The number of accelerations that coincided with the movements that were recorded was not very reliable or sensitive but it was accurate enough and predictive. The number of movements that accompanied the accelerations when added to the overall activity did become precise and predictive. Adding the two together make it more accurate and sensitive. New methods of monitoring are suggested, and these appear to be more simple and more efficient.
