Download or read book Heart Rate Variability Analysis with the R package RHRV written by Constantino Antonio García Martínez and published by Springer. This book was released on 2017-09-18 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the basic concepts of Heart Rate Variability (HRV) and its most important analysis algorithms using a hands-on approach based on the open-source RHRV software. HRV refers to the variation over time of the intervals between consecutive heartbeats. Despite its apparent simplicity, HRV is one of the most important markers of the autonomic nervous system activity and it has been recognized as a useful predictor of several pathologies. The book discusses all the basic HRV topics, including the physiological contributions to HRV, clinical applications, HRV data acquisition, HRV data manipulation and HRV analysis using time-domain, frequency-domain, time-frequency, nonlinear and fractal techniques. Detailed examples based on real data sets are provided throughout the book to illustrate the algorithms and discuss the physiological implications of the results. Offering a comprehensive guide to analyzing beat information with RHRV, the book is intended for masters and Ph.D. students in various disciplines such as biomedical engineering, human and veterinary medicine, biology, and pharmacy, as well as researchers conducting heart rate variability analyses on both human and animal data.

Download or read book Complex Systems and Computational Biology Approaches to Acute Inflammation written by Yoram Vodovotz and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The difficulty in achieving effective translation of basic mechanistic biomedical knowledge into effective therapeutics, is the greatest challenge in biomedical research. Nowhere is this more apparent than in the reductionist approaches to understanding and manipulating the acute inflammatory response in the settings of sepsis, trauma/hemorrhage, wound healing, and related processes. This book discusses complex systems and computational biology methods and approaches that have advanced sufficiently to allow for knowledge generation, knowledge integration, and clinical translation in the settings of complex diseases related to the inflammatory response. Well-regulated, self-resolving inflammation is necessary for the appropriate communication and resolution of infection and trauma, and for maintenance of proper physiology and homeostasis. In contrast, self-sustaining inflammation drives the pathobiology of the aforementioned diseases. It is now increasingly recognized that controlling and reprogramming inflammation in order to reap the benefits of this evolutionarily-conserved process is preferred to simply abolishing indiscriminately.

Download or read book Design Evaluation and Application of Heart Rate Variability Analysis Software HRVAS written by John T. Ramshur and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of heart rate variability (HRV) has become an increasingly popular and important tool for studying many disease pathologies in the past twenty years. HRV analyses are methods used to non-invasively quantify variability within heart rate. Purposes of this study were to design, evaluate, and apply an easy to use and open-source HRV analysis software package (HRVAS). HRVAS implements four major categories of HRV techniques: statistical and time-domain analysis, frequency-domain analysis, nonlinear analysis, and time-frequency analysis. Software evaluations were accomplished by performing HRV analysis on simulated and public congestive heart failure (CHF) data. Application of HRVAS included studying the effects of hyperaldosteronism on HRV in rats. Simulation and CHF results demonstrated that HRVAS was a dependable HRV analysis tool. Results from the rat hyperaldosteronism model showed that 5 of 26 HRV measures were statistically significant (p

Available in PDF, EPUB and Kindle. Book excerpt: There are few clinical problems in the sleep medicine field that are more challenging than the sleep difficulties experienced by individuals suffering from post-traumatic stress disorder (PTSD). This book offers a unique, complete resource addressing all the basic concepts and clinical applications in sleep medicine in settings where combat-related PTSD is commonplace. Authored by leading international experts in the field of sleep/military medicine, Sleep and Combat-Related Post Traumatic Stress Disorder is organized in six sections and provides a broad perspective of the field, from the established theories to the most recent developments in research, including the latest neuroscientific perspectives surrounding sleep and PTSD. The result is a full assessment of sleep in relation to combat-related PTSD and a gold standard volume that is the first of its kind. This comprehensive title will be of great interest to a wide range of clinicians -- from academics and clinicians working within or in partnership with the military health care system to veteran hospital physicians and all health personnel who work with war veterans.

Download or read book Heart Rate Variability Analysis During an Endurance Mountain Trail Race written by Miquel Cancio Hoppmann and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The autonomic nervous system (ANS) is the control mechanism of heart rate variability (HRV). Assessing HRV can lead to prominent information about this control system, taking into account the two control sympathetic and vagal branches. HRV can be evaluated by analyzing RR time series (consecutive heart beats) from linear methods in time and frequency domain in order to extract HRV indexes. Moreover, it is known that heart rate dynamics is not strictly linear, this is the reason that analyzing HRV dynamics by non-linear techniques can provide additional and essential information to the ANS. This project focuses on the quantification of several linear and non-linear metrics from athletes' RR recordings obtained during a trail and rest conditions, concretely, the days before and after this effort under supine and orthostatic positions.
Download or read book Robust Heart Rate Variability Analysis Using Gaussian Process Regression written by Siddharth S. Shah and published by . This book was released on 2011 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Heart rate variability (HRV) is a non-invasive way of measuring autonomic nervous system dynamics as influenced by one's emotional state. By studying beat to beat variations, the dynamic process regarding homeostasis can be studied. Quantication of HRV in frequency domain has traditionally been done in two ways: rstly, interpolating the unevenly sampled inter-beat intervals to a xed number of samples followed by applying Fast Fourier Transform and secondly by using Lomb's periodogram. In this thesis, a dierent approach is presented. Gaussian Process Regression (GPR) is used in order to interpolate the inter-beat intervals (training data set) to get a mean and variance bound, thus quantifying the time domain tachogram. This tachogram is then used as input to a FFT in order to characterize the frequency domain of HRV. The quantication of HRV using Gaussian Process Regression and Lomb's Periodogram is compared in lossy data conditions and in the presence of motion artifacts. The results show that GPR based FFT technique is less susceptible to outliers than lomb's periodogram. The eect of outliers and techniques for their removal are discussed for GPR based processing.
