Key result
Maternal respiration modeling suggests that low incidence of fetal-maternal heart-rate coordination at low breathing rates is explained by heart-rate characteristics, whereas higher incidence at fast rates is due to other factors.

Modeling results are hypothesis-generating and should not alter fetal monitoring; prospective studies needed to validate mechanisms at varying maternal breathing rates.
Computational modeling indicates that fetal-maternal heart-rate coordination at low maternal breathing rates is driven by intrinsic heart-rate characteristics, while coordination at high breathing rates involves additional mechanisms.
Leeuwen et al. (2009) studied Pregnancy. Maternal respiration rate was evaluated on Incidence of short-term fetal-maternal heart-rate coordination epochs. Maternal respiration modeling suggests that low incidence of fetal-maternal heart-rate coordination at low breathing rates is explained by heart-rate characteristics, whereas higher incidence at fast rates is due to other factors.
