Inter-Electrode Pulse Wave Velocity: A Direct Method for Maternal Arterial Stiffness Assessment During Pregnancy Using Multi-Channel ECG
Nicolas B. Garnier, Marlene J. E. Mayer, Clara Becker +3
Objective: To validate a novel inter-electrode pulse wave velocity (PWV) method that measures pulse propagation between ECG electrodes without left ventricular ejection time (LVET)…
Prenatal Stress Detection from Electrocardiography Using Self-Supervised Deep Learning: Development and External Validation
Martin G. Frasch, Marlene J. E. Mayer, Clara Becker +4
Prenatal psychological stress affects 15-25% of pregnancies and increases risks of preterm birth, low birth weight, and adverse neurodevelopmental outcomes. Current screening relie…
Measuring the time-scale-dependent information flow between maternal and fetal heartbeats during the third trimester
Nicolas B. Garnier, Maria S. Molinet, Marta C. Antonelli +2
Prenatal maternal stress alters maternal-fetal heart rate coupling, as demonstrated by the Fetal Stress Index derived from bivariate phase-rectified signal averaging. Here, we exte…
Heart Rate Variability Patterns Reflect Yoga Intervention in Chronically Stressed Pregnant Women: A Quasi-Randomized Controlled Trial
Marlene J E Mayer, Nicolas B Garnier, Clara Becker +3
Prenatal maternal stress (PS) is a risk factor for adverse offspring neurodevelopment. Heart rate variability (HRV) complexity provides a non-invasive marker of maternal autonomic…
