Computerized analysis of episodic changes in fetal heart rate variation in early labor

Fetal heart rate variation in early labor was measured by computerized analysis in cyclic episodes of low or high variation in 136 women at 37 to 42 weeks' gestation. The amplitude (mean ± SE) in episodes of low variation was 20.6 ± 0....

Zusammenfassung:Fetal heart rate variation in early labor was measured by computerized analysis in cyclic episodes of low or high variation in 136 women at 37 to 42 weeks' gestation. The amplitude (mean ± SE) in episodes of low variation was 20.6 ± 0.4 milliseconds; in high variation it was 57.3 ± 1.1 milliseconds. The duration (mean ± SE) of low episodes (24.3 ± 1.3 minutes) was less than that of high episodes (45.1 ± 2.7 minutes) but was sometimes >1 hour. In episodes of low variation the amplitude was
