[Fetal bradycardia during pregnancy. Apropos of 2 cases without fetal distress].

The authors report two cases of fetal bradycardia discovered at the beginning of the 8th month. The pregnancy history was normal. Sonography was helpful in the etiological diagnosis. It concerns a case of atrial extrasystole and another case of physiological bradycardia. The evolution was satisfactory with normal, spontaneous, vaginal delivery. During the pregnancy, the tracing combined a severe bradycardia around 80, a flat rhythm and an areactive rhythm. There was alternation with normal rhythms. The pregnancy history was reassuring. At the beginning of labor, the cardiac rhythm was normal. In the opposite case, vaginal delivery could only be advocated after determination of the capillary pH.
