Other software packages also deserve comment, such as the Kubios-HRV. To perform this task, many programming languages are employed, such as Matlab, Java, or even LabView. The common factor for all the algorithms aimed at helping clinicians in the HRV analysis is the fact that the majority of them have been implemented by particular investigation groups, which are forced to develop their own and proprietary software, due to the lack of a common software package, easily accessible and downloadable, that fulfills the particular requirements of each research association. This has conducted providers of medical technology at excluding this type of analysis in their devices, and researchers depend on software applications in order to apply additional processing methods. Īt the present moment, HRV analysis has not been established as a standard method for diagnosis.
Distinct techniques have been proposed in this area, such as spectral analysis, non-lineal techniques or time-domain methods. HRV analysis has been a very active research field for the last twenty years. The typical HRV spectrum of a healthy person at rest is mainly composed of two components: a low frequency band (LF), from 0.04 to 0.15 Hz and a high frequency band (HF) ranging from 0.15 to 0.4 Hz. Since then, its clinical usefulness in various pathologies such as myocardial infarction, hypertension, heart failure, transplantation, etc, has been studied. This relationship was experimentally determined by Aselkrod in 1981. Variability is the result of a trade-off between the influence of the parasympathetic system (accelerating the heart rate) and the sympathetic system (slowing the heart rate).
Heart Rate Variability (HRV) can be defined as the variations in the sequence of periods between consecutive heartbeats, and it is regulated by factors extrinsic to the circulatory system. This project is maintained by milegroup Table of contents
