Simple Summary The zoological community continually looks for new ways to improve the
management of the animals under their professional care. This includes finding …

Measurement of heart rate variability (HRV) is a non-invasive technique that can be used to
investigate the functioning of the autonomic nervous system, especially the balance …

According to classical concepts of physiologic control, healthy systems are self-regulated to
reduce variability and maintain physiologic constancy. Contrary to the predictions of …

A defining but elusive feature of physiologic systems is their daunting complexity. This
complexity arises from the interaction of a myriad of structural units and regulatory feedback …

Under basal resting conditions most healthy physiologic systems demonstrate highly
irregular, complex dynamics that represent interacting regulatory processes operating over …

This study examined chronic and short-term stress effects on heart rate variability (HRV),
comparing time, frequency and phase domain (complexity) measures in 50 healthy adults …

Altered variability in the cardiovascular system is associated with a range of cardiovascular
diseases and increased mortality. Because blood pressure and heart rate show distinct low …

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 …

In a normal human life span, the heart beats about 2–3 billion times. Under diseased
conditions, a heart may lose its normal rhythm and degenerate suddenly into much faster …

Анализ вариабельности сердечного ритма (ВСР) в настоящее время является одним
из самых популярных методов в медицине и физиологии. Ежемесячно публикуются …
