[Effect of caffeine on fetal heart rate and caffeine consumption habits in pregnant patients].

Responsiveness to caffeine was studied in early human fetal hearts surviving in nutrient solution. Alterations of the spontaneous contraction rate were followed. Three concentrations (0.01, 0.1 and 1 mmol/l) were applied. In the presence of caffeine there was a significant age- and concentration-dependent increase in fetal heart rate in the period of the… CONTINUE READING
