Introduction: The preterm born infant's ability to regulate its cerebral blood flow (CBF) is
crucial in preventing secondary ischemic and hemorrhagic damage in the developing brain …

Heart rate turbulence (HRT) is a phenomenon discovered during the mid-to late 1990s by
Georg Schmidt's group in Munich (Schmidt et al., 1999). Their study of sinus rhythm …

Objectives: This study sought to evaluate cardiac baroreflex sensitivity (BRS) as a predictor
of response to renal sympathetic denervation (RDN). Background: Catheter-based RDN is a …

In the pregnant mother and her fetus, chronic prenatal stress results in entrainment of the
fetal heartbeat by the maternal heartbeat, quantified by the fetal stress index (FSI). Deep …

Objective Recent studies suggest that phase‐rectified signal averaging (PRSA), measured
in antepartum fetal heart rate (FHR) traces, may sensitively indicate fetal status; however, its …

Objective Decreased fetal heart rate variability is associated with higher perinatal morbidity
and mortality in intrauterine growth restriction (IUGR). This study used a new method [phase …

Methods Cardiovascular autonomic nervous system assessment (eg, electrocardiogram and
beat-to-beat systolic blood pressure [SBP]) was performed the seated upright position at rest …

In preterm infants, a better understanding and quantification of cardiorespiratory coupling
may help improve caregiving by enabling the tracking of maturational changes and …

We systematically compare strengths and weaknesses of two methods that can be used to
quantify causal links between time series: Granger-causality and Bivariate Phase Rectified …

Purpose Prenatal stress (PS) during pregnancy affects in utero-and postnatal child brain-
development. Key systems affected are the hypothalamic–pituitary–adrenal axis and the …
