Background: Emotion is composed of cognitive processing, physiological response and
behavioral reaction. Heart rate variability (HRV) refers to the fluctuations between …

This pilot study investigated the differences of heart rate variability (HRV) indices between
two opposite emotion states: happiness and sadness, to reveal the differences of autonomic …

Heart rate variability (HRV) is a measurement of the fluctuation of time between each
heartbeat and reflects the function of the autonomic nervous system. HRV is an important …

The work presented in this paper aims at assessing human emotion recognition by means of
the analysis of the heart rate variability (HRV) with varying spectral bands based on …

The use of heart rate variability (HRV) in research has been greatly popularized over the
past decades due to the ease and affordability of HRV collection, coupled with its clinical …

Heart rate variability (HRV) is a critical marker of a healthy organism. Low HRV predicts
greater morbidity and mortality after heart attack, and also predicts death by all causes. HRV …

Heart rate variability (HRV) supports emotion regulation and is reduced by alcohol. Based
on the resonance properties of the cardiovascular system, a new 0.1‐Hz methodology was …

Heart rate variability (HRV) is the rate of variability between each heartbeat with respect to
time. It is used to analyse the Autonomic Nervous System (ANS), a control system used to …

Heart rate variability (HRV) analysis is commonly used as a quantitative marker depicting
the activity of autonomous nervous system (ANS) that may be related to mental stress. For …

Heart rate variability (HRV) analysis is a noninvasive tool widely used to assess autonomic
nervous system state. The market for wearable devices that measure the heart rate has …
