Cardiac Autonomic Dysfunction and Incidence of de novo Atrial Fibrillation: Heart Rate Variability vs. Heart Rate Complexity

Wessel, Niels; Berg, Karsten; Kraemer, Jan; Gapelyuk, Andrej; Rietsch, Katrin; Hauser, Tino; Kurths, Jürgen; Wenzel, Dave; Klein, Norbert; Kolb, Christof; Belke, Roberto; Schirdewan, Alexander; Kääb, Stefan

BackgroundThe REACT DX registry evaluates standard therapies to episodes of long-lasting atrial tachyarrhythmias and assesses the quality of sensing and stability of the lead and the implantable cardioverter-defibrillator ...

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; 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 ...

Quantifying Effects of Pharmacological Blockers of Cardiac Autonomous Control Using Variability Parameters

Miyabara, Renata; Berg, Karsten; Kraemer, Jan; Baltatu, Ovidiu Constantin; Wessel, Niels; Campos, Luciana A.

Objective: The aim of this study was to identify the most sensitive heart rate and blood pressure variability (HRV and BPV) parameters from a given set of well-known methods for the quantification of cardiovascular autonomic ...

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; 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 ...
