Electronic fetal monitoring technology is capable of monitoring and recording maternal heart rate (MHR) patterns that mimic fetal heart rate (FHR) patterns. The ability to distinguish one from the other requires knowledge of FHR and MHR characteristics and monitoring technology. Application of this knowledge may prevent fetal injury and death. ...

We encountered two cases of severe intrauterine hemorrhage associated with congenital intestinal atresia. In both cases, the first sign that necessitated immediate clinical management was the abnormal fetal heart rate patterns, represented by prolonged bradycardias and late decelerations. This occurred immediately after the onset of labor. An emergency cesarean section ...

Antepartum fetal monitoring based on the classical cardiotocography (CTG) is a noninvasive and simple tool for checking fetal status. Its introduction in the clinical routine limited the occurrence of fetal problems leading to a reduction of the precocious child mortality. Nevertheless, very poor indications on fetal pathologies can be inferred ...

Patterning of the ventral head has been attributed to various cell populations, including endoderm, mesoderm, and neural crest. Here, we provide evidence that head and heart development may be influenced by a ventral midline endodermal cell population. We show that the ventral midline endoderm of the foregut is generated directly ...
