Although analysis of heart rate variability is widely used for the assessment of autonomic
function, its fundamental framework linking low-frequency and high-frequency components …

In the assessment of autonomic function by heart rate variability (HRV), the framework that
the power of high-frequency component or its surrogate indices reflects parasympathetic …

Lower heart rate variability (HRV) is associated with a higher risk of cardiovascular events
and mortality, although the extent of the association is uncertain. We performed a meta …
