Instantaneous Cardiac Baroreflex Sensitivity: xBRS Method Quantifies Heart Rate Blood Pressure Variability Ratio at Rest and During Slow Breathing

Wessel, Niels; Gapelyuk, Andrej; Weiß, Jonas; Schmidt, Martin; Kraemer, Jan F; Berg, Karsten; Malberg, Hagen; Stepan, Holger; Kurths, Jürgen

Spontaneous baroreflex sensitivity (BRS) is a widely used tool for the quantification of the cardiovascular regulation. Numerous groups use the xBRS method, which calculates the cross-correlation between the systolic ...

Spontaneous baroreflex sensitivity: sequence method at rest does not quantify causal interactions but rather determines the heart rate to blood pressure variability ratio

Wessel, Niels; Gapelyuk, Andrej; Kraemer, Jan F; Berg, Karsten; Kurths, Jürgen

Objective: In order to quantify spontaneous baroreflex sensitivity (BRS) many groups use the sequence method (SME). In this paper we test the hypothesis that SME is quantifying causal interactions of pontaneous BRS at rest ...
