TL;DR: MSE analysis of HR, SBP and DBP oscillations is able to detect subtle abnormalities in cardiovascular control in young patients with DM and is independent of standard linear measures.

TL;DR: The finding of lower respiratory sinus arrhythmia, indicating a cardiovagal dysfunction in obese adolescents, can provide important diagnostic information about early subclinical autonomic dysfunction in obesity.

TL;DR: Parameters of RP should be used together with linear HRV parameters for better description of heart rate dysregulation in patients with diabetics, as RQA parameters are independent of overall HRV.

TL;DR: Assessing directional cardiovascular interactions among the basic variability signals of RR, SBP and diastolic blood pressure (DBP), using an approach which allows direct comparison between bivariate and multivariate coupling measures finds that bivariate measures better quantify the overall information transferred between variables, while trivariate measures better reflect the existence and delay of directed interactions.

TL;DR: A consistent increase in the baroreflex coupling strength from SBP to RR during head-up tilt, an insensitivity of the coupling strength along the non-baroreflex direction to both stressors, and no significant effect of mental arithmetics on the feedback coupling strength indicate that the proportion of causal interactions between SBP and RR significantly varies during different conditions.
