Heart Rate Variability Analysis with the R package RHRV (Use R!)

by Xosé A. Vila Leandro Rodríguez-Liñares Constantino Antonio García Martínez Abraham Otero Quintana María José Lado Touriño Jesús María Rodríguez Presedo Arturo José Méndez Penín

This book introduces readers to the fundamental 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 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. The second edition of the book has been updated to RHRV version 5.0. This version introduces a functionality to perform heart rate variability analysis on entire populations. This functionality automates and streamlines both the calculation of HRV indices in the time, frequency, and nonlinear domains, as well as the subsequent statistical analysis.

Heartificial Intelligence

by John Havens

As we program machines to be more like humans, how will they know what we value, if we don't know ourselves?The notion of robots gaining consciousness is beginning to become a reality, but the future of human happiness is dependent on our ability to teach machines what we value the most today. Featuring pragmatic solutions drawing on economics, emerging technologies, and positive psychology, Heartificial Intelligence provides a road map to help readers embrace the present and better define their future. Using fictional vignettes to help readers relate to larger concepts, this book paints a vivid portrait of how our lives might look in either a dystopia of robot dominance or a utopia where we use technology to enhance our natural abilities and evolve into a long-lived, super-intelligent, and caring species.ta that can be mined to reveal not just our buying habits and patterns, but how these patterns are impacted by our mood, the time of year, our location, and our interests?As Havens points out in H(app)inomics, the future needn't look so grim. Indeed, if we can wrest control of our personal data from corporations and use it to better understand ourselves, Havens argues, then we can combat this looming future and make love of life our most important personal economy.
