Heart rate variability (HRV) is a known risk factor for mortality in both healthy and patient
populations. There are currently no normative data for short‐term measures of HRV. A …

This review examines the influence on heart rate variability (HRV) indices in athletes from
training status, different types of exercise training, sex and ageing, presented from both …

In recent years more studies are using nonlinear dynamics to describe cardiovascular
control. Because of the large dispersion of physiological data, it is important to have large …

The application of methods drawn from nonlinear and stochastic dynamics to the analysis of
cardiovascular time series is reviewed, with particular reference to the identification of …

Purpose: To determine whether measuring heart rate variability (HRV) in a group of septic
patients without multiple organ dysfunction syndrome (MODS) made it possible to predict …

Heart rate variability (HRV) is a non‐invasive indicator of cardiac autonomic modulation at
rest. During rhythmic exercise, global HRV decreases as a function of exercise intensity …

There is little doubt that moderate training improves cardiac vagal activity and thus has a
cardioprotective effect against lethal arrhythmias. Our purpose was to learn whether a higher …

Regular physical exercise is an important factor to reduce the indexes of cardiovascular and
all causes morbimortality. However, there is, apparently, additional and independent …

The purpose of the present study was to determine if autonomic heart rate modulation,
indicated by heart rate variability (HRV), differs during supine rest and head-up tilt (HUT) …
