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

Power spectral analysis of heart rate variability has often been used to assess cardiac
autonomic function; however, the relationship of low‐frequency (LF) power of heart rate …

Components of heart rate variability have attracted considerable attention in psychology and
medicine and have become important dependent measures in psychophysiology and …

Heart rate variability (HRV) is a reliable reflection of the many physiological factors
modulating the normal rhythm of the heart. In fact, they provide a powerful means of …

studies as an index of vagal control of the heart and may be among the most selective …

This review examines how the sympathetic nervous system plays a major role in the
regulation of cardiovascular function over multiple time scales. This is achieved through …

Contemporary findings reveal that the multiple modes of autonomic control do not lie along a
