Exercise Effects on HRV in Cancer Patients
International Journal of Sports Medicine, 2012The present study evaluated the effects of physical exercise on heart rate variability (HRV) in cancer patients. 3 matched groups of each 15 tumour patients (60.4±8.9 years, 27 male, 18 female) were recruited: Physical exercise group 1 (acute treatment), Physical exercise group 2 (post treatment) and non-intervention group (acute treatment, no exercise)

Endurance Performance and Nocturnal HRV Indices
International Journal of Sports Medicine, 2009The effects of endurance training on endurance performance characteristics and cardiac autonomic modulation during night sleep were investigated. Twenty-four sedentary subjects trained over four weeks two hours per week at an average running intensity of 76+/-4% of their heart rate reserve.

Sample entropy-based HRV characterisation
International Journal of Medical Engineering and Informatics, 2012The non-linear methods-based heart rate variability analyses are widely becoming popular as these are based upon analysing original RR-interval series. The sample entropy (SampEn) is one of these methods used for quantifying signal complexity, and is based upon hypothesis that decreasing entropy is a pointer towards loss of heart rate variability (HRV).

Monitoring Driving Stress using HRV
2019 11th International Conference on Communication Systems & Networks (COMSNETS), 2019Driving stress is responsible for bad driving behavior and fatal accidents. This stress initiates from road factors and keeps negative consequences in overall traffic management as well as in transportation system. Bangladesh has poor road infrastructure, environment and management. We explore to know the Bangladeshi drivers stress level through HRV by

Improved HRV characterization using OCDWT
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009In this paper an over-complete discrete wavelet transform (OCDWT) algorithm, obtained by blending two wavelet transform implementations that is redundant wavelet transform and the Mallat's multiresolution decomposition, has been proposed to retrieve the time-varying characteristics of HRV under two different postures, supine and standing.

The HRV Analysis on e-Book Reading
2015In this study, the effects of four indoor illuminations on e-book readers are investigated by HRV analysis. Two main types of commercial light bulbs are adopted, the saving energy and LED ones. They are all categorized as high color temperature and low color temperature.

Analysis of HRV signal for disease diagnosis
2016 11th International Conference on Industrial and Information Systems (ICIIS), 2016This paper gives a brief comparison between some arrhythmias affected ECG signals with a normal sample of ECG recording. The comparison is based on the Heart Rate Variability (HRV) analysis. The HRV signal is generated from the ECG signal after detecting R-Peaks.
