Background Physical activity (PA) during pregnancy has been shown to be associated with several positive effects for mother, fetus, and offspring. Heart rate variability (HRV) is a noninvasive and surrogate marker to determine fetal overall health and the development of fetal autonomic nervous system. In addition, it has been shown to be significantly influenced by maternal behavior. However, the...
In this paper we try to explore the concepts of Heart Rate Variability using Photoplethysmographic (PPG) optical sensor. During this process we also try to detect the stress level of the subject from the HRV data. Our nervous system is very tightly connected with our heart. A normal person while resting will have heart rate from 60 to 90 beats per minute. But when a person is stressed the time duration...
The goal of this study was to investigate whether anxiety during pregnancy can be linked with the autonomic nervous system (ANS) via different heart rate variability (HRV) parameters. More than 100 pregnant women were included and underwent 24h ECG monitoring including a stress test and the state trait anxiety inventory (STAI) questionnaire, dividing them in a low, medium or high anxiety group. Standard...
