Book excerpt: About: Detailed discussion of the fundamental aspects of electrophysiology and includes over 70 case studies from an internationally recognzed group of contributors covering ECGs, SVTs, atrial fibrillation, ventricular tachycardia and more. Includes major contributions from Samuel Asirvatham, MD and Hein J. Wellens, MD. From the Preface: A plethora of significant new research and findings makes it difficult to keep up with the ever-changing field of electrophysiology. Despite these constant advances, there are fundamental aspects of the science that need to be understood by students of electrophysiology. This book was created to educate and uses cases and questions to keep the reader engaged. Chapter and case topics were chosen so that the information presented is useful for years to come. My associate editors and I are hopeful that this book will prove a useful tool for those interested in the field of electrophysiology. We also are very grateful to all the contributing authors for spending their time and effort to help create this handy but comprehensive and interesting work. Jasbir Sra, Milwaukee
