Key result
Maternal heart rate rises ~7 bpm from 16 to 34 weeks gestation while HRV decreases.
Why the study?
The autonomic nervous system plays a central role in physiological adaptation during pregnancy, causing normal changes in HRV. The study aimed to assess trends in HR and HRV parameters for remote maternal health monitoring during pregnancy and the 3-month postpartum period.
Does continuous smartwatch monitoring reveal trends in HR and HRV during pregnancy and the postpartum period?
Observational (n=58)

Does continuous smartwatch monitoring reveal trends in HR and HRV during pregnancy and the postpartum period?
p-value: p=<0.001
Continuous smartwatch monitoring demonstrates that heart rate increases and heart rate variability decreases as pregnancy proceeds, with values returning to normal after delivery.

Wearable HR/HRV monitoring provides normative pregnancy data; extends prior knowledge but remains hypothesis-generating pending outcome validation.
Sarhaddi et al. (2022) conducted an observational in Pregnancy and postpartum (n=58). Continuous monitoring using smartwatch (PPG) was evaluated on Heart rate trend during the second trimester (p=<0.001). Continuous monitoring revealed that heart rate increased by an average of 6.6 bpm from 16 to 34 weeks of gestation before decreasing, while heart rate variability parameters showed the inverse trend.
