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.

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

This important new book presents advancements in the treatment and prevention of Atrial Fibrillation (AF). The reader is provided with the latest information that is critically important in the daily care and for the potential cure of patients with AF. Each chapter deals with a different aspect of AF and each chapter is authored by internationally recognized experts in the evolving field of cardiac electrophysiology. This book is a single source that provides a multi-perspective look at and approach to AF. Because AF is so prevalent and affects all areas of medicine, the information in this book will be useful to all those in the medical field.

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 attack of atrial fibrillation experienced by President Bush of the United States attracted more attention from the general public to atrial fibrillation than ever before. Also, there is a growing body of knowledge of the pathophysiologic mechanism, the pathology and epidemiology, and especially of the thrombo-embolic complications of this arrhythmia, which is responsible for a renewed interest of the clinician in this very common human arrhythmia. These new perspectives on atrial fibrillation were presented during a conference on `Atrial Fibrillation, a Treatable Disease?', organized on May 7, 1992, in Amsterdam, the Netherlands. Atrial fibrillation is not the prerogative of the cardiologist only. Many practitioners from other areas in health care, in particular general physicians, internists and neurologists, are faced with this arrhythmia and its untoward consequences. This book bridges the gap between theory, experiment and the clinic. Emphasis is therefore on the selection of the optimal approach, including pharmacotherapy, catheter ablation, pacemaker and surgical therapy, based on the current scientific insights in the mechanism and prevention of atrial fibrillation.
