| Abstract: | Analysis of the fetal heart rate in 3,127 reactive nonstress tests revealed that the baseline rate decreased significantly between 28 and 41 weeks' gestation (6.4 beats per minute [4.5%]). Analysis of 235 women with two tests at least four weeks apart revealed that while the majority (51.1%) demonstrated a decrease, 26.8% experienced a rise in the baseline rate during the testing interval. |
