Evaluation of the influence of the autonomic nervous system on the ventricular repolarization
duration was carried out using beat-to-beat analysis of the time intervals between the peaks …

Background: Uterine activity (UA) monitoring is an essential element of pregnancy
management. The gold-standard intrauterine pressure catheter (IUPC) is invasive and …

Our objective was to assess the autonomic function of ALS patients with and without bulbar
signs to characterize dysautonomia in ALS disease. Standard autonomic tests and spectral …

Autonomic dysfunction seems to be involved in the progression and prognosis of congestive
heart failure. Measurement of heart rate variability (HRV) provides a noninvasive method to …

We studied a possible correlation between autonomic cardiac activity and the level of the
red blood cell acetylcholinesterase (AChE) in patients with probable Alzheimer disease …

The degree of reduction in heart rate variability (HRV) after myocardial infarction has been
shown to have prognostic significance, but HRV has not been studied extensively in patients …

Chronic hypoxaemia can play a pathological role in abnormalities of the autonomic nervous
system (ANS). In patients with chronic obstructive pulmonary disease (COPD), chronic …

Heart rate variability (HRV) provides useful information about heart dynamics both under
healthy and pathological conditions. Entropy measures have shown their utility to …

Chemoreflex stimulation elicits both hyperventilation and sympathetic activation, each of
which may have different influences on oscillatory characteristics of cardiovascular …

Postoperative atrial fibrillation, acute kidney dysfunction and low cardiac output following
coronary surgery are associated with morbidity and mortality. The purpose of this study is to …
