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.

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.

Dr Kusumoto’s unique new book takes a step-wise, patient-centered approach to guide readers through the thought process required during an electrophysiology study and the development of new findings. Follows a case based step-wise approach focused on the EP lab that allows readers to follow along with the thought process behind how experienced electrophysiologists first diagnose, then prepare, treat and manage patients with common rhythmic abnormalities, including atrial fibrillation Written by award-winning Mayo Clinic Physician-educator Dr. Fred Kusumoto Ideal for fellows, new EPs, nursing and technical staff in the EP lab Includes clinical questions to help readers test their understanding of the steps and concepts covered in the book and prepare for certification exams

Nothing is more perplexing to the clinician new to device therapy than having to deal with cardiac electrocardiograms from a device patient. Pacemakers and other implantable cardiac rhythm management devices leave their “imprint” on ECGs and can significantly change what clinicians see - or expect to see. Evaluating paced ECGs can be challenging, yet nowhere is it taught in any sort of comprehensive manner. Designed specifically for clinicians new to device therapy, The Nuts and Bolts of Interpreting Paced ECGs and EGMs offers practical, reliable and objective information on paced cardiac electrograms. Written in a lively, intelligent and easy to navigate style, emphasizing real-life clinical practice and practical tips, this book includes illustrated paced ECGs by skilled artists to help minimize “fuzzy” lines and emphasize key points. Each chapter concludes with a checklist of key points from each subject (“Nuts and Bolts”).

Edited by world-renowned cardiologist Kenneth Ellenbogen, MD, and collaboratively written by five expert physicians and allied health professionals, Essential Concepts of Electrophysiology and Pacing through Case Studies guides the reader in developing and refining the key skill of analyzing tracings – one of the most essential proficiencies in electrophysiology. With 60 cases comprising more than 140 tracings, figures, and tables and accompanied by multiple-choice questions, this scholarly yet eminently practical text delineates the core concepts and brings the reader directly into each case, offering EP physicians and fellows, device representatives and engineers, and other allied health professionals a fundamental understanding of the most important concepts on which the practice of EP is based. Appropriate for professionals with different levels of proficiency, Essential Concepts of Electrophysiology and Pacing through Case Studies includes a wide array of basic to advanced tracings that range from surface ECGs to pacemaker and ICD recordings to complex intracardiac tracings that will prove vital in strengthening and sharpening practical skills. Relevant references included with each case allow the reader to delve even deeper into the principles presented and will be invaluable in helping to prepare for IBHRE, ABIM, and other EP certification exams.

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.
