Heart Rate Variability in Sleep Studies

NORMALIZED SPECTRAL BAND POWERS/VARIANCES ARE DERIVED MEASURES REFLECTING AUTONOMIC ACTIVITY, COMMONLY COMPUTED IN MANY HEART rate variability (HRV) data analysis software packages available to sleep researchers, particularly for the low-frequency (LF: often 0.04-0.15 Hz) and high-frequency (HF: often 0.15-0.40 Hz) spectral power/variance bands. The normalized (or normalized unit) spectral indi...

Acute exposure to environmental tobacco smoke and heart rate variability.

Environmental tobacco smoke (ETS) has been associated with cardiovascular mortality. Pathophysiologic pathways leading from ETS exposure to cardiopulmonary disease are still being explored. Reduced cardiac autonomic function, as measured by heart rate variability (HRV), has been associated with cardiac vulnerability and may represent an important pathophysiologic mechanism linking ETS and risk ...

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...
