Rationale The effects of chronic moderate alcohol consumption on cardiac function are not
understood. Acute stress may affect cardiac function by shifting autonomic cardiac regulation …

Cardiac autonomic tone can be assessed either by estimating separately vagal and
sympathetic tones or by evaluating the net effect of their interaction, the so-called …

Objectives To examine the circadian pattern of cardiac autonomic modulation (CAM) and its
attributes in general population. Methods We obtained 24-h beat-to-beat RR data using a …

Theoretical perspectives and empirical evidence suggest that the parasympathetic nervous
system engages in active monitoring and moderating of inflammatory processes. A clearer …

In humans, there is a documented association between anxiety disorders and
cardiovascular disease. Putative underlying mechanisms may include an impairment of the …

New Findings What is the central question of this study? New measurements for
cardiovascular complexity, such as detrended fluctuation analysis (DFA) and multiscale …

Background An experimental setting and software were developed to evaluate
cardiovascular autonomic function in conscious rats. A restrained approach was used …

Background and Objectives: Recent studies in humans and dogs have shown that
ventricular repolarization exhibits a low-frequency (LF) oscillatory pattern following …

Analysis of heart rate variability (HRV) by nonlinear approaches has been gaining interest
due to their ability to extract additional information from heart rate (HR) dynamics that are not …

Heart rate variability (HRV), the change in the time intervals between adjacent heartbeats, is
an emergent property of interdependent regulatory systems that operate on different time …
