Key result
In computerized analysis of non-stress tests, the amplitude of fetal heart rate accelerations was a more significant component than duration (r2=0.998 for Acc15-15 vs Acc15-10, p<0.0001).
Why the study?
Is amplitude or duration a more significant component of fetal heart rate acceleration in non-stress test analysis?
Population
n=3055 normal fetal heart rate (FHR) tracings at 30-42 weeks' gestation

Amplitude may warrant priority in computerized NST algorithms; leaves open whether duration criteria can be safely revised.

Is amplitude or duration a more significant component of fetal heart rate acceleration in non-stress test analysis?
Effect estimate: r2 = 0.998
p-value: p=< 0.0001
In computerized non-stress test analysis, the amplitude of fetal heart rate accelerations is a more significant component than their duration.
Hoh et al. (2012) conducted an observational in Normal fetal heart rate tracings (n=3,055). Amplitude of fetal heart rate accelerations vs. Duration of fetal heart rate accelerations was evaluated on Correlation among fetal heart rate acceleration combinations (r2 = 0.998, p=< 0.0001). In computerized analysis of non-stress tests, the amplitude of fetal heart rate accelerations was a more significant component than duration (r2=0.998 for Acc15-15 vs Acc15-10, p<0.0001).
