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 …

Measures of heart rate variability (HRV) as a predictor of risk of disease and mortality have
been investigated from various perspectives for more than six decades. The aim of the …

Healthy biological systems exhibit complex patterns of variability that can be described by
mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals …

Understanding transient dynamics of the autonomic nervous system during fear learning
remains a critical step to translate basic research into treatment of fear‐related disorders. In …

Background Heart rate variability is used as an assessment method for cardiac autonomic
modulation. Since the Task Force's publication on heart rate variability in 1996, the …

Driver fatigue detection systems have potential to improve road safety by preventing crashes
and saving lives. Conventional driver monitoring systems based on driving performance and …

Heart rate variability (HRV) is the fluctuation in time between successive heartbeats and is
defined by interbeat intervals. Researchers have shown that short-term (∼ 5-min) and long …

Heart-rate variability (HRV) is frequently introduced as mirroring imbalances within the
autonomous nerve system. Many investigations are based on the paradigm that increased …

Background Heart rate variability, or the variation in the time interval between consecutive
heart beats, is a non-invasive dynamic metric of the autonomic nervous system and an …

Heart rate variability (HRV), the change in the time intervals between adjacent heartbeats, is
an emergent property of interdependent regulatory systems that operate on different time …
