[Congenital cardiac disease: cardiotocographic manifestations (author's transl)].

The Authors have studied in retrospect the cardiotocographic registrations of women who had given birth to foetus affected by congenital cardiac disease. The observations of several authors (Heinriche Seideschnur; Fischer) are confirmed that persistent bradycardia in pregnancy or in labour could be a sign of a congenital cardiac anomaly. Furthermore, the high incidence of C.T.G. alterations are noticed (in the form of decelerations and significant reduction of the oscillation amplitudes) in the registrations of foetus affected by such cardiac disease.

Topographic variations in EEG asymmetry during sleep.

EEG signals were recorded in 11 normal subjects from F4-C4, F3-C3, P4-O2 and P3-O1 during both stage 2 and the REM stage of each NREM/REM cycle. The logarithm of the right/left ratio for the power in the range of the various frequency bands showed a prevalent right-side asymmetry only with the fronto-central derivations. This trend, observed for all frequency bands, remained stable over the various NREM/REM cycles with the exception of the last one. These data indirectly support the hypothesis that the right hemisphere is more heavily involved in dreaming than the left, and suggest a prevalent involvement of the anterior regions.
