Fish Consumption, Sleep, Daily Functioning, and Heart Rate Variability

Heart rate variability during nap sleep.

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...

Dietary Fish and -3 Fatty Acid Consumption and Heart Rate Variability in US Adults

Consumption of fish and -3 fatty acid reduces risk of cardiac death, but mechanisms are not well established. Heart rate variability (HRV) predicts cardiac death and reflects specific electrophysiological pathways and influences. To elucidate electrophysiological influences and support effects on clinical risk, we evaluated the associations between habitual consumption of fish and marine -3 fat...

Dietary Fish and -3 Fatty Acid Consumption and Heart Rate Variability in US Adults

Background—Fish and -3 fatty acid consumption reduce risk of cardiac death, but mechanisms are not well established. Heart rate variability (HRV) predicts cardiac death and reflects specific electrophysiological pathways and influences. We hypothesized that habitual consumption of fish and marine -3 fatty acids would be associated with more favorable HRV, elucidating electrophysiological influe...

Heart rate variability and level of personality functioning

In the DSM-5 manual a new dimensional system for Personality Disorders was included in section III. We aimed to pave way for a biological validation of this dimensional system by measuring base line heart rate variability (HRV) in a group of patients vs controls already assessed with the Level of Personality Funciotning Scale (LPFS). HRV is a measure of vagal tone linked to emotional regulation...
