Summary

This book is designed to answer the clinically relevant questions most frequently posed by trainees, practitioners and support staff. Self-assessment questions allow the reader to assess his or her knowledge of the material presented in each chapter and references, provided at the end of each chapter, highlight key articles from the current medical literature so that readers who desire to do so can delve deeper into various subjects in electrophysiology. Written by an electrophysiologist and a nurse, the book is designed to appeal to a wide range of trainees, from cardiac care nurses who want more than cursory knowledge of electrophysiology, to cardiology fellows beginning their specialization in electrophysiology.
