This issue of Cardiac Electrophysiology Clinics devoted to syncope a disorder that is associated with increased mortality. Internationally recognized experts discuss the many causes of syncope, helping the clinician to distinguish life-threatening etiologies from benign ones.

Debates and controversies about how to treat difficult problems or conditions abound in cardiac electrophysiology.? This issue attempts to bring together a variety of controversial subjects and to present differing views on how to resolve these questions so clinicians will have a handy guide to the most current thinking about these difficult subjects.

Cardiac electrophysiologists face many challenging situations in which there is no clear-cut answer about the best way to handle a particular clinical problem. This issue brings together articles on many such situations, presents arguments on both sides, and lets the reader conclude which is the best way to manage a particular patient.? Among the controversial and debatable topics included are how to handle device recalls, optimal timing for assessment of ICD efficacy, extraction o f broken leads, and anticoagulation therapy in device patients.

In the rapidly evolving field of treating cardiac arrhythmias, the importance of direct management of patients with implantable cardiac devices is growing. The devices have become increasingly complex, and understanding their algorithms and growing programming options is essential for physicians who implant and manage them.

Atrial fibrillation (AF) is the most common sustained arrhythmia, affecting approximately 2.3 million people in the US. One of the most serious side effects of AF is embolic stroke. Technology developed in the last 10 years has made AF treatable and potentially curable. This issue discusses many of the clinical issues in the management of AF, including cardioversion, anticoagulation, and ablation. Also included are current guidelines for treatment and a view of the future.

Advancements in the treatment and prevention of Atrial Fibrillation are presented in this important new book. Atrial Fibrillation affects approximately 2.5 million individuals in the United States and is projected to affect 15 million individuals by 2050. In Atrial Fibrillation: From Bench to Bedside, the reader is provided with the latest information that is critically important in the daily care and for the potential cure of patients with Atrial Fibrillation. Each chapter deals with a different aspect of Atrial Fibrillation and was 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 Atrial Fibrillation. Because Atrial Fibrillation is so prevalent and affects all areas of medicine, the information in this book will be useful to cardiologists, cardiac surgeons, researchers, and all those in the medical field.

Implantable defibrillators as originally conceived by Michel Mirowski were limited to the detection and automatic termination of ventricular fibrillation. In the original "AID" device, the detection algoritlun sought to distinguish sinus rhytlun from ventricular fibrillation by identifying the "more sinusoidal waveform of ventricular fibrillation. " The therapeutic intervention was elicited only once deadly polymorphic rhythms had developed. It was rapidly learned, however, that ventricular fibrillation is usually preceded by ventricular tachycardia. Mirowski recognized the pivotal importance of developing algoritllms based on heart rate. Ventricular tachycardia detection allowed the successful development of interventions for the termination of ventricular tachyarrhythmias before they degenerated into ventricular fibrillation. Current device therapy no longer confines itself to tlle termination of chaotic rhythms but seeks to prevent them. Diagnostic algorithms moved upward along the chain of events leading to catastrophic rhytlulls. Rate smoothing algorithms were developed to prevent postextrasystolic pauses from triggering ventricular and atrial tachyarrhytlmlias. Beyond the renaissance of ectopy-centered strategies, long-term prevention received increasing attention. Multisite pacing therapies provided by "Arrhythmia Management Devices" were designed to reduce the "arrhytlunia burden" and optimize the synergy of cardiac contraction and relaxation. Clinical evidence now suggests that atrial fibrillation prevention by pacing is feasible and tllat biventricular pacing may be of benefit in selected patients with heart failure. However, these applications of device therapy that generally require ventricular defibrillation backup remain investigational and were not considered in this book.

In the United States, 50-60 individuals suffer a cardiac arrest each hour, amounting to approximately 250,000 deaths every year. In the first five minutes of a cardiac arrest, ventricular tachycardia (VT) and ventricular fibrillation are the most frequent cardiac arrhythmias encountered. Despite emergency medical response systems, the long-term survival from out-of-hospital cardiac arrest remains poor in most US cities. Paramount to achieving successful resuscitation of a cardiac arrest victim is providing early defibrillation. This issue of Cardiac Electrophysiology Clinics covers a full spectrum of issues related to sudden cardiac death, including the epidemiology of sudden cardiac death, advances in CPR, the implantable cardiac defibrillator (ICD), and VT ablation.

Atrial fibrillation is the most common sustained arrhythmia in humans. An incredible worldwide effort from physicians, scientists and industry over the last decade has brought forth new insights and therapeutic tools. We are fortunate to have achieved a level of understanding about this complex disease that we can indeed cure some patients. While we proceed at full speed ahead looking for cures for the rest, we have taken this opportunity in the Medical Clinics of North America to reflect on how much we have learned and on the task that lies ahead. This issue opens with a historical perspective, discusses many of the clinical issues in the management of atrial fibrillation, such as cardioversion, anticoagulation and ablation, and concludes with the current guidelines for treatment and a view of the future.

Focusing on anatomy and procedural strategy for atrial fibrillation and ventricular tachycardia, this atlas uses pictures and schematic diagrams to show how to use intracardiac echo (ICE) to assess anatomy, guide ablation, and prevent complications during interventional procedures, pulmonary vein stenosis, and embolic events. The authors review the state of the art and background support in the use of ICE in interventional electrophysiology procedures and the anatomy of both the atrial and ventricular chambers. They discuss innovative indications in the EP laboratory, future technologies such as 3-D echocardiography, and the integration of ICE with other types of imaging technology.

Clinical cardiac electrophysiology is one of the most rapidly expanding fields in cardiology. There are currently no comprehensive case based books in this field. A Case Review of Cardiac Electrophysiology is a case based review of cardiac electrophysiology. The aim of this book is to provide a comprehensive case based review of cardiac electrophysiology. It will include implantable device cases as well as ablation cases and difficult clinical cases and may be used as a useful review in cardiac electrophysiology for those taking board examinations. There will also be cases that will be useful for associate professionals working in the field of cardiac electrophysiology including those individuals working for industry.
