[Comparative intranatal and postnatal electrocardiography in normal labor].
The comparison of intranatal and postnatal electrocardiograms shows, that in spite of the hemodynamic important transposition of the infant circulation are no remarkable differences in the electrocardiogram. Remarkable is also the resemblance of electrical axises in the intranatale and postnatale ECG, at which we report particularly on the estimation of the electrical axis of the fetal heart, introduced by Larks. The estimation of this axis in the fetal ECG and its position call the attention as additional diagnostical criterion in some cases to an intrauterine fetal distress or a congenital heart disease.
