Research suggests that there is a connection between sleep apnea and heart palpitations, especially at night. Though this condition generally lowers the rate, it can also lead to brief bursts of increased heart rate. Healthy adults should have rates between 60 to 100 beats per minute. If it ri...
We determined whether alterations in heart rate dynamics during sleep in patients with chronic fatigue syndrome (CFS) differed from controls and/or correlated with changes of sleepiness before and after a night in the sleep laboratory. We compared beat-to-beat RR intervals (RRI) during nocturnal ...
In this paper, we study some aspects of the heart rate variability (HRV) of subjects with normal sinus rhythm (NSR) during wake and sleep phases. To this end, a structure function is employed to quantify the fluctuations of the heart rhythm, which is subsequently used to interpret the HRV...

What is normal heart rate variability (HRV) range? See how HRV changes by age and gender and calculate your normative HRV scores.
As a2017 overview of heart rate variabilityputs it, “ a healthy heart is not a metronome.” Instead, the rhythms of your heart can and should vary as your body adapts to situational stimuli. “Beat-to-beat fluctuations are best described by mathematical chaos.” ...
Correlated and uncorrelated regions in heart-rate fluctuations during sleep. Healthy sleep consists of several stages: deep sleep, light sleep, and rapid eye movement (REM) sleep. Here we show that these sleep stages can be characte... A Bunde,S Havlin,JW Kantelhardt,... - 《Physical Review...

The aim of this study was to investigate fluctuations in heart rate variability (HRV), which reflect autonomic nervous system (ANS) function and potential psychological and physical strain, among 24 health care workers during work and sleep during four consecutive extended work shifts. Data included...
