Heart rateis the number of times the heart beats per minute. HRV is a measure of the change in timing between successive heartbeats. Having variation in heart rate is not only completely normal but also necessary. Your heart is constantly keeping blood flow at a consistent level, keeping pace...
The determination of the normal heart rate variability (HRV) range\nin the time and frequency domain with a commercially available Holter\nmonitoring system in a group of carefully selected normal subjects is\naddressed. Spectral analysis of HRV using the fast Fourier\ntransformation technique ...
Heart rate is the number of times the heart beats each minute. Daily activities can change how fast or slow the heart beats – from a slow, steady beat while resting or sleeping to a higher rate during exercise. "There's a wide variation in what a normal heart rate can be depending ...

We could show that the differences between stages observed in healthy subjects were still present in subjects with apnea despite their cyclical variation in heart rate. We conclude, that detrended fluctuation analysis is able to separate the influences of stages and apnea on heart rate variability. ...
The analysis showed that one person's mean daily resting heart rate may differ by up to 70 beats per minute from another person's normal rate. Taken together, age, sex, body mass index (BMI), and average daily sleep duration accounted for less than 10 percent of the observed variation be...
Analysis of heart rate variation (HRV) has become a popular noninvasive tool for assessing the activities of the autonomic nervous system (ANS). HRV analysis is based on the concept that fast fluctuations may specifically reflect changes of sympathetic and vagal activity. It shows that the structu...
