From master teacher George J. Klein, MD, this stepwise book is for those with a working knowledge of electrophysiology who have looked at a complicated ECG or intracardiac tracing and drawn a blank, not recognizing a pattern from their personal experience, and without a good idea of how to proceed or venturing a guess with variable confidence. Dr. Klein presents strategies that he has found useful, not just by providing an “answer,” but also exploring how he solved the problem with a systematic approach using “tools” of analysis that applies to both ECGs and EGM tracings.

The ECG remains the cornerstone of arrhythmia diagnosis, even after an explosion of technology and rapid expansion of our understanding of arrhythmia mechanisms. While many traditional textbooks emphasize cataloguing arrhythmias and pattern recognition, this book by internationally recognized professor George J. Klein, MD, presents a universally applicable systematic approach to ECG arrhythmia diagnosis based on careful measurement and identification of key events and exploring their expected electrophysiological underpinnings. There is fundamentally no difference in the principles and strategies behind understanding the ECG and intracardiac tracings—both are absolutely complementary. Over 90 case studies with tracings in full landscape format are used to highlight important principles, with each case providing an important diagnostic “tip” or teaching point.A multiple-choice question is provided with each tracing not only to “frame the problem” for the reader but to provide some practice and strategies for answering cardiology board examination-type questions.An important book that paves the way to understanding ECGs when preparing for board or certification exams. The book is meant for serious students of arrhythmias, be they cardiology or electrophysiology trainees or established physicians.

Organized to present a comprehensive overview of the field of cardiology in an accessible, reader-friendly format that can be covered in about 12 months, this new edition contains roughly 50% new material, the cardiac pharmacology section has been completely reworked, cardiovascular trials have been included, and the entire book has been updated to reflect current practice guidelines and recent developments. The book is peppered throughout with numerous tables and clinical pearls that aid the student, as well as the teacher, to remain focused.

Although the electrocardiogram (ECG) is accepted as a standard clinical tool, electrograms (EGMs) recorded during electrophysiology studies are considered complex and confusing. In this brief paperback, an award-winning teacher provides the newcomer with an introductory guide to electrophysiology studies and the interpretation of electrograms. Dr. Kusumoto divides the 15 chapters into two main sections, Electrophysiology Concepts and Specific Arrhythmias. First, he reviews the basics of electrophysiology testing and the diagnostic evaluation of general types of arrhythmias. From that foundation, he proceeds to discuss specific arrhythmia types and techniques for evaluation and ablation: • Accessory pathways • AV node reentry • Focal atrial tachycardia • Atrial flutter • Atrial fibrillation • Ventricular tachycardia The final chapter considers implantable cardiac devices as they relate to ECGs and electrograms. Each short chapter includes a bullet-point summary and helpful review questions. Plentiful ECG and EGM tracings illustrate the text. Cardiology and electrophysiology fellows, allied professionals working in the electrophysiology laboratory, and all professionals interested in beginning a study of heart rhythms and electrophysiology will want to keep Understanding Intracardiac EGMs and ECGs close at hand for frequent reference.

This volume of intracardiac tracings builds on our first book, Essential Concepts of Electrophysiology and Pacing through Case Studies, that guides the reader in developing and refining the key skill of analyzing electrophysiologic recordings. Over 60 cases with a focus on intracardiac EGMs are presented as board exam cases and questions. Tracings are framed by a question, followed by annotated tracings, and a discussion of the correct and potential answers. Cases present a full range of difficulty from simple to advanced. This book will provide a valuable review for a wide variety of professionals — physicians, associated professionals, nurses and technicians — preparing for certification and re-certification examinations in electrophysiology.

From senior electrophysiologist and world-class educator George Klein, a fully illustrated guide with over 100 intracardiac tracings and figures that allow the physician to approach electrophysiologic problems effectively and systematically. The book is especially focused on electrophysiological maneuvers and provides a clear and understandable guide to their proper selection and interpretation using abundant clinical examples. Defines the integral role for "traditional" electrogram (EGM) analysis in order to understand the mechanism of a tachycardia. It goes without saying that a correct arrhythmia diagnosis is a prerequisite to catheter ablation regardless of the presence of sophisticated mapping and imaging technologies. Electrophysiological maneuvers are fundamental to this process, and proper selection and interpretation of maneuvers constitute a core skill of the electrophysiologist. In this volume, we make the case that most maneuvers are fundamentally similar in principle and can be understood by appreciating a few basic physiological and anatomical principles. The art lies not in a comprehensive knowledge by rote of every maneuver or its application, but rather a systematic approach using common principles. We illustrate this by showing abundant examples and emphasizing the "game plan," including checklists that can be applied to virtually any maneuver. —George J. Klein In my opinion, this book should be on the shelf of every electrophysiologist trainee as well as every clinical cardiac electrophysiologist. It is a classic, like its editor. Dr. Klein deserves high praise for organizing his and his colleagues’ clinical experiences and thought processes into a concise, practical text that should be part of all training programs in electrophysiology. —From the foreword by Mark E. Josephson, MD
