Background Heart rate variability (HRV) is an important marker of heart health, with low
values reflecting reduced vagal control of the heart rhythm. Objective The purpose of this …

Given the widespread incidence of smoking as well as its deleterious health effects, it is

The measurement and analysis of heart rate variability (HRV), which is based on the
variation between consecutive NN intervals, has become an established procedure over the …

Background and Objective: Heart rate variability (HRV) as an index of the autonomic
nervous system appears to be related to reactivity to experimental pain stimuli. HRV could …

Objective Psychosocial stress is associated with substantial morbidity and mortality.
Accordingly, there is a growing interest in biomarkers that indicate whether individuals show …

The dynamical fluctuations in the rhythms of biological systems provide valuable information
about the underlying functioning of these systems. During the past few decades analysis of …

Heart rate variability (HRV) has been associated with various diseases and reflects
autonomic cardiac control sensitive to central nervous system function. Examples of the …

The intimate connection between the brain and the heart was enunciated by Claude
Bernard over 150 years ago. In our neurovisceral integration model we have tried to build on …

BACKGROUND: Depression is associated with an increase in the likelihood of cardiac
events; however, studies investigating the relationship between depression and heart rate …

In the recent years, short-term heart rate variability (HRV) describing complex variations of
beat-to-beat interval series that are mainly controlled by the autonomic nervous system …
