ABSTRACT
A longitudinal study was carried out on 38 women with low risk pregnancies. These women had cardiotocography at 27-28 wk initially, at fortnightly intervals thereafter until 36 wk and at weekly intervals thereafter until delivery. All cardiotocographs were analyzed by one investigator who was not aware of the individual clinical situation. Of the 232 cardiotocographs, 12 (0.5%) of poor quality were excluded from analyses. The mean base-line heart rate decreased from 142.5 (SD 6.03) beats per min at 27-30 wk to 138.2 (SD 7.4) at term. Analysis of variance for repeated measures showed that the decrease in foetal heart rate with gestation was statistically significant (P < 0.001). The number of accelerations increased with gestation (P = 0.002). There were no significant changes in variability and decelerations with increasing gestation.
