We are pleased to launch this 4th edition after increasing levels of demand from readers and practitioners all over the world. This newest edition tracks the rapid and exciting development of new mapping/ imaging/catheter technologies and ablation techniques in our rapidly changing field. We could not have prepared this text without the valuable input from countless readers, and we continue to welcome your comments, criticisms, and feedback to improve future editions of this book. Major changes in this edition include the addition of several innovative chapters and new authors, particularly in the areas of atrial fibrillation and ventricular tachycardias. We also removed obsolete content and updated every chapter to match the latest in field knowledge and application methods, such as fundamental concepts of biophysics and parameters of radiofrequency lesion formation and cryothermal ablation, ablation-related anatomy, pathophysiology and diagnoses of arrhythmias, as well as 3-dimensional mapping/image-guided ablation techniques of common and uncommon arrhythmias. We also provided troubleshooting tips for helpful guidance in difficult cases. In addition to hundreds of detailed figures and tables, the number of online videos has been substantially expanded to facilitate access to and ease of learning. We retained some features from prior editions including the same chapter format for consistency in organizational structure and content presentation.
We continued our work with experienced, skilled, and acclaimed subject matter experts to write and review each chapter. Finally, we remained committed to casting a wide readership net and aimed to make this book readily accessible to all levels of cardiac electrophysiologists, trainees, and allied health professionals. We envision this book to be a powerful and authoritative reference tool for the office; a practical guide for patient care, teaching, and preparation for the board examination in clinical cardiac electrophysiology; a comprehensive and trustworthy manual for an ablation procedure; and a valuable and accessible resource in every electrophysiology laboratory. We also hope that this book will help the next generation of practitioners be better equipped to overcome challenges and succeed in the expanding field of cardiac electrophysiology.
