Measures of heart rate variability (HRV) are major indices of the sympathovagal balance in
cardiovascular research. These measures are thought to reflect complex patterns of brain …

In this paper we present a method to predict sudden cardiac death (SCD) based on the heart
rate variability (HRV) signal and recurrence plots and Poincaré plot-extracted features. This …

Methods. We identified patients from a database maintained by our organ procurement
organization (LifeSource). Brain death was declared according to a hospital protocol in …

A patient assessed by heart rate variability (HRV) methodology, beginning just after the
completion of brain death (BD) diagnosis, showed remaining very low frequency (VLF) …

The muscle fatigue can be expressed as decrease in maximal voluntary force generating
capacity of the neuromuscular system as a result of peripheral changes at the level of the …

OBJECTIVE: To assess the autonomic nervous system (ANS) in coma by heart rate
variability (HRV). METHODS: Sixteen comatose patients and 22 normal subjects with …

Intensive care unit (ICU) experienced and skillful people in this field should be employed
because the equipment, facilities, and admitted patients have more special conditions than …

BACKGROUND: Heart rate turbulence, deceleration capacity (DC), and symbolic dynamics
(SD) are promising novel domains of autonomic indices representing the multidimensional …

The functional assessment and prediction of outcome of subjects with severe disorder of
consciousness such as those in the vegetative (VS) or minimally conscious (MCS) states …

The over-arching purpose of this thesis was to investigate whether an intervention that
teaches a person to mediate their physiological stress response can also improve decision …
