A methodology to quantify the differences between alternative methods of heart rate variability measurement
(Institute of Physics (IOP), 2015-12-14)
Article
Open AccessThis work proposes a systematic procedure to report the differences between heart rate variability time series obtained from alternative measurements reporting the spread and mean of the differences as well as the agreement ... -
Agreement between two photoplethysmography-based wearable devices for monitoring heart rate during different physical activity situations: a new analysis methodology
(Nature, 2022-09-14)
Article
Open AccessWearables are being increasingly used to monitor heart rate (HR). However, their usefulness for analyzing continuous HR in research or at clinical level is questionable. The aim of this study is to analyze the level of ... -
An application of fractional differintegration to heart rate variability time series
(2013-07)
Article
Restricted access - publisher's policyFractional differintegration is used as a new tool to characterize heart rate variability time series. This paper proposes and focuses in two indexes (ac and fnQ) derived from the fractional differintegration operator. ... -
Reduced heart rate variability predicts fatigue severity in individuals with chronic fatigue syndrome/myalgic encephalomyelitis
(2020-01-06)
Article
Open AccessHeart rate variability (HRV) is an objective, non-invasive tool to assessing autonomic dysfunction in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). People with CFS/ME tend to have lower HRV; however, in the ...
