Book Synopsis Poincaré Plot Methods for Heart Rate Variability Analysis by : Ahsan Habib Khandoker
Download or read book Poincaré Plot Methods for Heart Rate Variability Analysis written by Ahsan Habib Khandoker and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Poincaré plot (named after Henri Poincaré) is a popular two-dimensional visualization tool for dynamic systems due to its intuitive display of the dynamic properties of a system from a time series. This book presents the basis of Poincaré plot and focus especially on traditional and new methods for analysing the geometry, temporal and spatial dynamics disclosed by the Poincaré plot to evaluate heart rate variability (HRV). Mathematical descriptors of Poincaré plot have been developed to quantify the autonomic nervous system activity (sympathetic and parasympathetic modulation of heart rate). Poincaré plot analysis has also been used in various clinical diagnostic settings like diabetes, chronic heart failure, chronic renal failure and sleep apnea syndrome. The primary aims of quantification of the Poincaré plots are to discriminate healthy physiological systems from pathological conditions and to classify the stage of a disease. The HRV analysis by Poincaré plot has opened up ample opportunities for important clinical and research applications. Therefore, the present book can be used either for self-study, as a supplement to courses in linear and nonlinear systems, or as a modern monograph by researchers in this field of HRV analysis.
Book Synopsis Heart Rate Variability: Clinical Applications and Interaction between HRV and Heart Rate by : Karin Trimmel
Download or read book Heart Rate Variability: Clinical Applications and Interaction between HRV and Heart Rate written by Karin Trimmel and published by Frontiers Media SA. This book was released on 2015-10-07 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, assessment of heart rate variability (HRV) has increased in various fields of research. HRV describes changes in heartbeat intervals, which are caused by autonomic neural regulation, i.e. by the interplay of the sympathetic and the parasympathetic nervous systems. The most frequent application of HRV is connected to cardiological issues, most importantly to the monitoring of post-myocardial infarction patients and the prediction of sudden cardiac death. Analysis of HRV is also frequently applied in relation to diabetes, renal failure, neurological and psychiatric conditions, sleep disorders, psychological phenomena such as stress, as well as drug and addiction research including alcohol and smoking. The widespread application of HRV measurements is based on the fact that they are noninvasive, easy to perform, and in general reproducible – if carried out under standardized conditions. However, the amount of parameters to be analysed is still rising. Well-established time domain and frequency domain parameters are discussed controversially when it comes to their physiological interpretation and their psychometric properties like reliability and validity, and the sensitivity to cardiovascular properties of the variety of parameters seems to be a topic for further research. Recently introduced parameters like pNNxx and new dynamic methods such as approximate entropy and detrended fluctuation analysis offer new potentials and warrant standardization. However, HRV is significantly associated with average heart rate (HR) and one can conclude that HRV actually provides information on two quantities, i.e. on HR and its variability. It is hard to determine which of these two plays a principal role in the clinical value of HRV. The association between HRV and HR is not only a physiological phenomenon but also a mathematical one which is due to non-linear (mathematical) relationship between RR interval and HR. If one normalizes HRV to its average RR interval, one may get ‘pure’ variability free from the mathematical bias. Recently, a new modification method of the association between HRV and HR has been developed which enables us to completely remove the HRV dependence on HR (even the physiological one), or conversely enhance this dependence. Such an approach allows us to explore the HR contribution to the clinical significance of HRV, i.e. whether HR or its variability plays a main role in the HRV clinical value. This Research Topic covers recent advances in the application of HRV, methodological issues, basic underlying mechanisms as well as all aspects of the interaction between HRV and HR.

Book Synopsis Perspectives on Behavioral Inhibition by : J. Steven Reznick
Download or read book Perspectives on Behavioral Inhibition written by J. Steven Reznick and published by University of Chicago Press. This book was released on 1989-11-09 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral inhibition, often displayed as shyness in children and avoidance in animals, can be observed in the earliest stages of infancy. Recent research indicates that in extreme cases the tendency to either approach or withdraw from uncertain events continues through late childhood and is supported by specific biological mechanisms, suggesting a genetic basis. To effectively study behavioral inhibition, researchers are departing from the essentially experiential and descriptive techniques of traditional psychology and turning to a multidisciplinary approach that integrates psychology, psychiatry, epidemiology, genetics, and ethology. Perspectives in Behavioral Inhibition brings together the most current research of leading scholars in the various disciplines involved.
Book Synopsis Muscle Recovery After Exercise, Training and Competition: Physiological Indicators and Non-invasive Monitoring Techniques by : Alessandro Moura Zagatto
Download or read book Muscle Recovery After Exercise, Training and Competition: Physiological Indicators and Non-invasive Monitoring Techniques written by Alessandro Moura Zagatto and published by Frontiers Media SA. This book was released on 2020-05-21 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire to improve muscle function and prevent overuse injuries from exercise and throughout training has led to the development of various methods to aid recovery and track readiness to perform. Ergogenic aids such as cold-water immersion, massage, and dynamic recovery procedures may have positive effects but the results of the related research remain equivocal. Furthermore, novel interventions in this scenario, like compression garments, ice vests, and photobiomodulation therapy are promising but need more evidence-based data to support their effectiveness. Similarly, to properly monitor individual physical conditioning, there is a growing interest toward unobtrusive measures to accurately represent physiological status during and/or after exercise. There are several techniques being used, such as subjective ratings of well-being, heart rate monitoring, hormonal and hematological profile assessments. However, more sensitive indexes like heart rate variability and muscle activation (voluntary and/or involuntary) are arising as attractive alternatives that may delineate physical conditioning status and readiness to perform more precisely than the aforementioned measures. The purpose of this Research Topic is to critically evaluate and summarize recent data from observational and intervention studies related to non-invasive methods designed to promote recovery and objectively monitor training status. Their association to physical performance and physiological recovery in athletes during training and competition is a major focus of this Topic.

Book Synopsis Multiscale Entropy Approaches and Their Applications by : Anne Humeau-Heurtier
Download or read book Multiscale Entropy Approaches and Their Applications written by Anne Humeau-Heurtier and published by MDPI. This book was released on 2020-11-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiscale entropy (MSE) measures to evaluate the complexity of time series by taking into account the multiple time scales in physical systems were proposed in the early 2000s. Since then, these approaches have received a great deal of attention and have been used in a wide range of applications. Multivariate approaches have also been developed. The algorithms for an MSE approach are composed of two main steps: (i) a coarse-graining procedure to represent the system’s dynamics on different scales and (ii) the entropy computation for the original signal and for the coarse-grained time series to evaluate the irregularity for each scale. Moreover, different entropy measures have been associated with the coarse-graining approach, each one having its advantages and drawbacks. In this Special Issue, we gathered 24 papers focusing on either the theory or applications of MSE approaches. These papers can be divided into two groups: papers that propose new developments in entropy-based measures or improve the understanding of existing ones (9 papers) and papers that propose new applications of existing entropy-based measures (14 papers). Moreover, one paper presents a review of cross-entropy methods and their multiscale approaches.

Book Synopsis Assessing Complexity in Physiological Systems through Biomedical Signals Analysis by : Paolo Castiglioni
Download or read book Assessing Complexity in Physiological Systems through Biomedical Signals Analysis written by Paolo Castiglioni and published by MDPI. This book was released on 2021-03-02 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complexity is a ubiquitous phenomenon in physiology that allows living systems to adapt to external perturbations. Fractal structures, self-organization, nonlinearity, interactions at different scales, and interconnections among systems through anatomical and functional networks, may originate complexity. Biomedical signals from physiological systems may carry information about the system complexity useful to identify physiological states, monitor health, and predict pathological events. Therefore, complexity analysis of biomedical signals is a rapidly evolving field aimed at extracting information on the physiological systems. This book consists of 16 contributions from authors with a strong scientific background in biomedical signals analysis. It includes reviews on the state-of-the-art of complexity studies in specific medical applications, new methods to improve complexity quantifiers, and novel complexity analyses in physiological or clinical scenarios. It presents a wide spectrum of methods investigating the entropic properties, multifractal structure, self-organized criticality, and information dynamics of biomedical signals touching upon three physiological areas: the cardiovascular system, the central nervous system, the heart-brain interactions. The book is aimed at experienced researchers in signal analysis and presents the latest trends in the complexity methods in physiology and medicine with the hope of inspiring future works advancing this fascinating area of research.
