Assessing the Cardiovagal Baroreflex
… and lengthening, respectively, of the R-R interval. This phenomenon, otherwise known as the cardivagal baroreflex, is best described by the sigmoid relationship between R-R interval length and systolic blood pressure. The linear portion of this relationship is used to derive the slope or …

Synchronization, Variability, and Nonlinearity Analysis: Applications to Physiological Time Series
… lung injury. We discover that periodicity of R-R interval is a key to distinguish difference of HRV in two ventilation groups. For nonlinearity analysis, we attempt to distinguish a nonlinear dynamical system from nonlinear transformation of a linear system. We investigate a nonlinear detection …
