“…Also, we did not control for potential covariation of maternal and fetal heart rate. However, other research indicates that fetal and maternal heart rates are not correlated (Gavin, Kogutt, Fletcher, & Szymanski, ). Another potential limitation is lack of fetal weight and growth data; males tend to be heavier at birth than females (de Zegher, Devlieger, & Eeckels, ), and as fetuses develop, they show a more mature pattern of autonomic functioning.…”

Researchers have reported associations between fetal sex and heart rate (FHR) and heart rate variability (FHRV) but rarely in the context of fetal behavioral sleep state. We examined differences in measures of fetal autonomic function by sex and sleep state. Fetal abdominal ECG monitoring technology was used to measure FHR and two measures of FHRV—standard deviation of FHR (SD) and beat‐to‐beat variability (RMSSD). FHR and movement patterns were also recorded with standard Doppler ultrasound monitor technology employed to code sleep states. Data were collected from 82 healthy fetuses ranging from 36 to 39 weeks gestation. A one‐way MANOVA showed that FHR was significantly lower and SD was significantly higher for males than females. Independent samples t tests found that these sex differences were only in the active sleep state. There were no significant differences in RMSSD by sex. Repeated measures MANOVA for a subset that exhibited more than one state (N = 22) showed that SD was significantly different by state. RMSSD showed a marginally significant sleep state difference. In conclusion, fetal sex differences in HR and HRV may indicate more mature autonomic functioning in near‐term males than females and fetal sleep state can influence abdominal fECG derived measures of FHR and FHRV.

“…Despite the issues with signal detection noted here, fECG technology allows prolonged fetal monitoring in settings that would not be possible with fCTG. These include during polysomnography or maternal nocturnal sleep, as part of this report and those by others (DiPietro, Raghunathan, et al., 2021; Lucchini et al., 2020; Stone et al., 2017), physical activity, such as yoga (Gavin et al., 2020), and as women engage in daily activities (Kapaya et al., 2016; Sletten et al., 2018). As such, there can be an appropriate trade‐off between participant loss due to inability to detect a fECG signal and the ability to address certain research questions that require prolonged or more naturalistic settings…”

Fetal heart rate variability is a key indicator of fetal neurodevelopment and well‐being. Most studies have relied on Doppler‐based fetal cardiotocography (fCTG) but recent technologies have made fetal electrocardiography (fECG) more widely available. We compared simultaneous recordings of fCTG and fECG in 131 fetuses twice during gestation (28 and 36 weeks) using a commercially available device (Monica AN24). Within‐individual correlations for fetal heart rate values, based on averaged data during 50‐min recordings, neared 1.0. Continuous and episodic measures of variability were also correlated, particularly at 36 weeks. Data collected during maternal polysomnography at 36 weeks were used to evaluate reliability of variability measures collected during the 50‐min recording. Both fCTG‐ and fECG‐derived measures of variability exhibited correspondence with variability during maternal presleep wakefulness and most sleep states. Results did not appreciably differ by data source or method used to calculate variability. fECG monitoring presented challenges, particularly at 28 weeks, when recordings with signal loss of ≤30% were available from only 27% of participants. Success rates improved to 84% at 36 weeks. fCTG was successful in over 90% of participants at each gestational age. Considerations in the selection of fECG versus fCTG in developmental research are discussed.

“…Die fetale Herzaktion war in keinem der Fälle suspekt oder pathologisch. In der Anstrengungsphase wurden bei allen Schwangeren unregelmäßige Uteruskontraktionen aufgezeichnet, die jedoch in der Meditations-und Ruhephase nicht mehr auftraten [6]. Im Vergleich zu nicht depressiven Schwangeren weisen depressive Schwangere zudem ein erhöhtes Risiko für das Auftreten einer postpartalen Depression, verminderten Sexualerlebens sowie postpartalen Stress auf [5].…”
