title: Analysis of the influence of diurnal variation in maternal movements on fetal heart rate acceleration.
abstract: To determine the influence of diurnal variation in maternal movements (MM) on fetal heart rate (FHR) accelerations, 24-hour maternal heart rates (MHR), MM and FHR recordings were made simultaneously on nine healthy pregnant women at 36-39 weeks of gestation. Correlations between the diurnal variations in maternal factors and FHR parameters; that is, baseline FHR, amplitude, duration and hourly percentage of time spent in accelerations, were examined. Only a few cases showed a significant correlation between acceleration parameters and the diurnal variation of MHR or MM, while most cases indicated a high correlation between the diurnal variation in baseline FHR and that of maternal factors. In conclusion, the occurrence and form of accelerations might be independent of maternal activity.
