[Actocardiography in obstetrics]

Introduction of ultrasonic techniques made more detailed follow-up of the motor activity of the foetus in its natural environment possible. The objective of the submitted paper is to present actocardiography as a method which makes it possible to visualize differences of motor activity of the foetus, in particular during the third trimester and to map different types of movements. The authors obtained thus objective records in a group of pregnancies which will be suitable for comparison with the motor activity of foetuses with signs of hypoxia, with foetuses with retarded growth or foetuses threatened by other risks. This method can be thus included and used as a method of routine in the spectrum of examinations of imminent foetal stress.
