Available in PDF, EPUB and Kindle. Book excerpt: Atrial Fibrillation from an Engineering Perspective provides an up-to-date overview of techniques developed for acquisition, modeling, and analysis of noninvasive, bioelectrical signals reflecting this common arrhythmia. Special emphasis is put on emerging technologies for monitoring of atrial fibrillation in connection with ischemic stroke, interventional ablation procedures, and pharmacological treatment, applications which all depend on the availability of techniques for detecting and characterizing episodes of paroxysmal atrial fibrillation. Detectors exploring both rhythm and morphology are described, as well as detectors confined to rhythm and better suited for low power implementation. A wide variety of approaches to modeling and characterization of atrial activity are described, emanating from a statistical and deterministic starting points. This book is suitable for graduate students, researchers, and engineers who want a comprehensive treatise of atrial fibrillation from an engineering perspective. It may be used for self-study, as a supplement to courses in signal processing, or as a modern monograph by researchers in the field of atrial fibrillation.

Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of atrial fibrillation has increased significantly. Several focal areas within the heart which trigger atrial fibrillation have been identified by physicians. There are a number of ways to lessen and treat atrial fibrillation. Ablating the focal areas is one of the therapies to alleviate or stop the symptoms, especially using radiofrequency as an energy source to perform the ablation. Before performing the radiofrequency ablation, an electrophysiologist needs to acquire cardiac information in as much detail as possible. This information includes heart surface geometry, electrical activation sequences, electrical activities times and volumes, etc. A successful radiofrequency ablation requires precise cardiac geometry reconstruction and accurate focal areas localization. A number of novel computer-aided 3-dimension cardiac reconstruction mapping technologies are able to integrate with Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and body surface ECG to provide comprehensive cardiac anatomical structures and information to users during the overall ablation procedure. These cardiac mapping systems also provide real-time cardiac information to operators and identify the complex fractionated atrial electrograms (CFAEs) for ablation purposes. The principles of fluoroscopy-based cardiac images heart surface reconstruction are reviewed. An optimization algorithm (Hill climbing algorithm) is introduced to approach and identify the CFAEs.

This book was released on 2015-03-12 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atrial Fibrillation: A Multidisciplinary Approach to Improving Patient Outcomes, provides a current and comprehensive update on path physiology, epidemiology, management strategies of rate control, pharmacologic and nonpharmacologic approaches to rhythm control, risk stratification for stroke and bleeding, anticoagulant therapy, and left atrial occlusion devices. The contributions by experienced internists, cardiologists, electrophysiologists, surgeons, anesthesiologists, pharmacists, internists, nurse practitioners, and nurse educators provide a unique perspective. Case studies of paroxysmal, persistent, and permanent atrial provide clinical context incorporating recent evidence and best practices for the multidisciplinary approach to improving patient outcomes. “The physician is inundated with information, and needs all of this to be reduced and summarized in a readable form. This cannot be done simply by technical editing because it involves real expertise to pick the “jewels for the crown.” This has been accomplished so well by the authors who have contributed to this book. The result is a gem — a source of enlightenment for all the many clinicians who care for patients suffering from this ubiquitous arrhythmia. I read it from cover to cover in about three hours, and learned much which is new and useful to my practice. It is the best small book that I know dealing with this big subject.” -From the foreword by A. John Camm, MD

Download or read book Understanding Atrial Fibrillation written by Peter Spector and published by John Wiley & Sons. This book was released on 2019-08-05 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new guide to the mechanisms and principles behind the world’s most common abnormal heart rhythm Affecting 30 million or more people across the globe, atrial fibrillation is one of the most prevalent – and yet misapprehended – issues facing modern cardiology. Its potential causes and optimal treatment strategies are matters of some conjecture in the medical community, where ongoing research has yielded findings that can prove challenging to those not familiar with the complex physiology at the root of the condition. Recognizing these concerns, distinguished electrophysiologist Peter Spector has designed Understanding Atrial Fibrillation as a means by which to equip clinicians with the data and analytic tools needed to develop a better grasp of this arrhythmia’s full nature. The book begins by providing a detailed explanation of atrial fibrillation’s causal mechanisms and builds its exploration from there. Working toward an up-to-date knowledge of the mapping and ablation of atrial fibrillation, its chapters assess the experimental data that has shaped current thoughts on the condition and then outline the best methods with which to interpret that rich but potentially difficult information. This revelatory new guide: Explores hypotheses of multiple drivers and mechanisms co-existing in individual patients Addresses common misperceptions and inaccurate views about atrial fibrillation Describes the basic physiology of atrial fibrillation’s propagation and reentry Explores the various mechanisms and higher-order dynamics of fibrillation Discusses how to intervene and alter atrial physiology to prevent fibrillation Understanding Atrial Fibrillation is truly an invaluable resource for physicians, fellows, residents, electrophysiology lab staff, and all other practitioners involved in the diagnosis and treatment of atrial fibrillation.
Download or read book New Perspective in Atrial Fibrillation written by Charles Guenancia and published by Mdpi AG. This book was released on 2021-08-18 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the large volume of associated research, the pathophysiological mechanisms involved in atrial fibrillation (AF) onset and recurrence remain uncertain. This may explain why the performances of thromboembolic and bleeding prediction scores in AF patients are limited. In the past few years, the concept of atrial cardiopathy has emerged as a promising lead to connect AF to stroke, heart failure, and inflammatory processes: indeed, all of the mechanisms associated with atrial remodeling and the development of atrial cardiopathy are also likely to promote the development of AF. This recent concept of atrial cardiopathy suggests that the real trigger of stroke may be an abnormal atrial substrate rather than atrial rhythm itself. In this setting, AF could be seen as a symptom of atrial cardiopathy rather than a risk factor of stroke. In the absence of validated clinical markers of atrial cardiopathy, the search for the mechanism of AF remains the cornerstone of cardioembolic stroke prevention for now. The aim of this Special Issue is to gather basic research as well as pathophysiological and epidemiological papers focused on the relationship between atrial substrates and atrial fibrillation onset, recurrence, and outcomes.
