[Cardiotocographic monitoring in pregnancy: some cases of sporadic decelerations (author's transl)].

The Authors are refering to the appearance of unknown deceleration in "APC" cardiotocograms. There is no relationship between these decelerations and the uterine contractions or fetal movements. These decelerations are called "sporadic" and are an indication of fetal risk. However, it is not necessary to have an immediate delivery.
