Novel metric for non-invasive beat-to-beat blood pressure measurements demonstrates physiological blood pressure fluctuations during pregnancy

HIGHLIGHTS

• What: The authors aim to establish the concept of two-dimensional signal warping an approved method from ECG signal processing for non-invasive continuous BP signals. One aim of this study was to characterize the reaction of fetal autonomic regulation to maternal paced breathing based on a contextdependent biosignal analysis of ECG, PPG, BP, and other recorded signals. These models were designed to assess the connection between WOG groups 21-23, 24-25, 26-27, and 28-30 and corresponding changes in B2B-BPF. To exclude potential interaction effects of the breathing and orthostasis exercises, the initial . . .
