U-shaped patterns are acceleration-deceleration periods in RR interval series. These relatively short time events (average duration 29.8±4.1 s) are the most laminar structures in the night-time recordings. The aim of this study is a analysis of slee

Using information theoretic measures, interaction between heart rhythm, time series of diastolic intervals and repolarization in the ventricles is analyzed. Transfer entropy and joint transfer entropy are calculated. Results for a group of healthy in

Atrial fibrillation (AF) is related to a very complex local electrical activity reflected in the rich morphology of intracardiac electrograms. The link between electrogram complexity and efficacy of the catheter ablation is unclear. We test the hypot

Introduction: Heart rate variability (HRV) fluctuations have a wide frequency band and are a result of multiple contributing factors. In this study, we focused on laminar, U-shaped accelerations of heart rate — approximately 20–40 seconds long

One of the ways allowing to control the performance of the Autonomic Nervous System (ANS) is monitoring the cardiorespiratory coupling. It shows how the two most important systems in the human body act to function efficiently. The effect that is beli

Abstract Due to the prolonged inflammatory process induced by infection of the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), indices of autonomic nervous system dysfunction may persist long after viral shedding. Previous studies

Here, we present new results obtained from a 1-D model of the atrium, with both the sinoatrial (SA) and atrioventricular (AV) nodes included. This model is able to reproduce forward and backward propagation between the SA and AV node. These nodes wer

Several definitions of static entropies and coarse-grained entropy rates (CER’s) were used to analyze 24-hour RR interval sequences of three sex, age and disease matched control pairs. The matching was done with the assessment of the risk of cardia

This article evaluates the association of autonomic information flow (AIF) measures with dysfunction and prognosis in selected diseases and measures their circadian rhythms.
