Available in PDF, EPUB and Kindle. Book excerpt: Heart rate variability (HRV) analysis is a powerful non-invasive tool used to determine the state of the heart and assess the development of the Autonomic Nervous System (ANS). The reduced HRV has been associated with negative outcome of ANS. This work describes the results obtained by HRV analysis of two groups of children, 41 Intrauterine growth retarded (IUGR) and 34 normal for a period of 24 hours. The main objective of this work was to explore the autonomic control in IUGR children by performing HRV analysis and comparing the results with normal children to find differences in HRV at 10 years of age. Barker theory and hypothesis states that the IUGR can be prone to coronary heart diseases or hypertension in their adulthood. Signal processing was performed on the ECG signal (data) provided which included filtering and detecting the QRS to find the RR segments. In the time domain analysis many parameters were calculated for all 75 children. Several comparisons between IUGR and normal children groups using night time and one hour RR data collected at night using several variables were computed. Frequency domain analysis of RR has been performed by autoregressive model (AR) Fast Fourier Transform (FFT) after re-sampling RR data of all 75 children. Calculation of the frequency components, large frequency, high frequency, and ratio of LF/HF, were obtained using FFT, AR and Lomb periodogram. Statistical analyses were performed to compare between IUGR and normal children. Time and frequency analysis comparison between the two groups of children showed no significant statistical differences, but the analysis has shown significant difference when dividing IUGR into IUGR1 (

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.

Download or read book Heart Rate Variability and Anxiety in Children written by Dagong Ran and published by . This book was released on 2016 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated tonic heart rate variability (HRV) and heart rate variability reactivity in response to stress in children with anxiety and worry symptoms. Twenty-nine children age 8 to 12 from a rural Midwestern region completed the study and were included in the data analyses. Participants completed an artificial auditioning task in which they were asked to sing in front of a video camera. Electrocardiogram were recorded prior, during, and after the task. Frequency and time domain analyses of HRV were conducted. Neither parent-report or child self-report anxiety/worry symptom levels were associated with baseline frequency domain and time domain HRV. All participants showed similar HRV reactivity in response to the stress task. Specifically, high frequency HRV was higher during baseline than during stress task, and low frequency HRV was higher during baseline than both during stress task and recovery. These findings contradicted with previous literature results. More studies are needed to examine the association between anxiety and HRV in children.

Download or read book Clinical Assessment of the Autonomic Nervous System written by Satoshi Iwase and published by Springer. This book was released on 2016-09-08 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes newly developed methods of assessing the autonomic nervous system. Up-to-date information on microneurographic analysis of human cardiovascular and thermoregulatory function in humans, heart rate variability, and 131I-metaiodobenzylguanidine (MIBG) scintigraphy are provided. Microneurography, which was originally developed as a technique to analyze the afferent muscle spindle, came to be used to analyze sympathetic nerve activity in the mid-1980s. In the twenty-first century, this technique has become prevalent all over the world especially in investigating the pathophysiology of human cardiovascular function. It is also now used in researching human thermoregulatory function. Heart rate variability is another valuable tool in investigating the current status of human vagal function and in predicting future cardiovascular disease. MIBG is also used to assess cardiac noradrenergic function, especially decreases associated with Parkinson’s disease, Lewy body disease, and multisystem atrophy. Overviews of recent advances in these three important assessments are provided by leading experts.Clinical Assessment of the Autonomic Nervous System is a useful resource for neurologists and researchers of clinical neurophysiology.

This book was released on 2012-11-12 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate reference book : the 5th updated edition of the famous “blue guide”. Incluided : A DVD with new sequences completes each chapter! Epileptology changes. The syndromic approach is completed by an etiological approach, based on the major advances in genetics and functional genetics. New entities have found their place, and a purely descriptive, “electroclinical” approach is no longer adapted in many circumstances. The 5th edition of the Blue Guide includes the most recent advances. It was necessary to justify the physiological, epidemiologic, genetic and therapeutic approaches and to consider them in the light of the new classification efforts, which are still in the making. Nevertheless, the description of epileptic syndromes, both classical and recent, remains at the core of this book.

Download or read book Toxicological Effects of Methylmercury written by National Research Council and published by National Academies Press. This book was released on 2000-09-27 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.

Download or read book Development of executive function during childhood written by Yusuke Moriguchi and published by Frontiers Media SA. This book was released on 2016-04-01 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: Executive function refers to the goal-oriented regulation of one’s own thoughts, actions, and emotions. Its importance is attested by its contribution to the development of other cognitive skills (e.g., theory of mind), social abilities (e.g., peer interactions), and academic achievement (e.g., mathematics), and by the consequences of deficits in executive function (which are observed in wide range of developmental disorders, such as attention-deficit hyperactivity disorder and autism). Over the last decade, there have been growing interest in the development of executive function, and an expanding body of research has shown that executive function develops rapidly during the preschool years, with adult-level performance being achieved during adolescence or later. This recent work, together with experimental research showing the effects of interventions targeting executive function, has yielded important insights into the neurocognitive processes underlying executive function. Given the complexity of the construct of executive function, however, and the multiplicity of underlying processes, there are often inconsistencies in the way that executive function is defined and studied. This inconsistency has hampered communication among researchers from various fields. This Research Topic is intended to bridge this gap and provide an opportunity for researchers from different perspectives to discuss recent advances in understanding childhood executive function. Researchers using various methods, including, behavioral experiments, neuroimaging, eye-tracking, computer simulation, observational methods, and questionnaires, are encouraged to contribute original empirical research. In addition to original empirical articles, theoretical reviews and opinions/perspective articles on promising future directions are welcome. We hope that researchers from different areas, such as developmental psychology, educational psychology, experimental psychology, neuropsychology, neuroscience, psychiatry, computational science, etc., will be represented in the Research Topic.
