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.

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.

The book presents recent advances in signal processing techniques for modeling, analysis, and understanding of the heart's electrical activity during atrial fibrillation. This arrhythmia is the most commonly encountered in clinical practice and its complex and metamorphic nature represents a challenging problem for clinicians, engineers, and scientists. Research on atrial fibrillation has stimulated the development of a wide range of signal processing tools to better understand the mechanisms ruling its initiation, maintenance, and termination. This book provides undergraduate and graduate students, as well as researchers and practicing engineers, with an overview of techniques, including time domain techniques for atrial wave extraction, time-frequency analysis for exploring wave dynamics, and nonlinear techniques to characterize the ventricular response and the organization of atrial activity. The book includes an introductory chapter about atrial fibrillation and its mechanisms, treatment, and management. The successive chapters are dedicated to the analysis of atrial signals recorded on the body surface and to the quantification of ventricular response. The rest of the book explores techniques to characterize endo- and epicardial recordings and to model atrial conduction. Under the appearance of being a monothematic book on atrial fibrillation, the reader will not only recognize common problems of biomedical signal processing but also discover that analysis of atrial fibrillation is a unique challenge for developing and testing novel signal processing tools.

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

Atrial fibrillation is underdiagnosed and preventative strategies are underutilized. The disease is estimated to rise to an epidemic level, increasing by over 50% by the end of the decade, occurring commonly in the setting of otherwise “healthy” aging. Innovative Management of Atrial Fibrillation provides a forum for a full discussion on this topical matter. Distinguished experts from both electrophysiology and cardiac surgery place their work in the context of future development, examining the short-comings of current pharmacological treatments. This results in a unique, comprehensive review for cardiologists, cardiac surgeons and anyone who wishes to gain a complete perspective on the fast-paced field of atrial fibrillation. Material ranges from atrial pathophysiology to advanced minimally invasive surgical ablation and cutting edge palliative and curative therapeutic options. The book also includes the examination of innovative management strategies and the next generation of therapies, giving an essential insight into the emerging potential of gene therapy.
