[Effect of atropine on fetal heart rate]

The effect of atropine on the foetal heart rate (FHR) was examined in 56 normal pregnancies. 40 mcg/kg atropine was administered. According to the results of the examinations the FHR was not effected by atropine in the 8.--13. weeks of gestation. The FHR was effected by the applied dose of atropine only after the 17th week increasing over the physiological oscillation. In the course of pregnancy FHR was increased by atropine in every case it nearly raised to FHR values observed in the 8.--13 weeks still not effected by atropine.
