Summary
Study of pregnant women reveals altered circadian patterns in heart rate and HRV, with these rhythm parameters showing potential as biomarkers for pregnancy complications.
Methods
Continuous monitoring of HR and HRV circadian rhythms during pregnancy
Key Findings
- Autonomic nervous system regulates pregnancy adaptations
- HR and HRV circadian patterns change during pregnancy
- Circadian rhythm parameters may predict complications
- Non-invasive biomarker potential for maternal health
Limitations
Further research needed on complication prediction
What This Means for You
During pregnancy, your body's rhythms change significantly. Tracking HRV patterns over time—especially circadian variations—may help identify early warning signs of complications. Work with your healthcare provider to interpret any concerning patterns.
