Table of Contents


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.


With considerable gratitude to him, I dedicate this book encapsulating an approach to the analysis of ECG and EGM tracings to my old friend and colleague Mark E. Josephson (1943–2017). He is, of course, universally known for his role in bringing the exciting but largely theoretical field of electrophysiology to clinical application, and his book of electrophysiology, Clinical Cardiac Electrophysiology: Techniques and Interpretation, is widely acknowledged to be the “bible” of electrophysiology.


However, I don’t think I would get too much disagreement from generations of trainees and students in saying that his major love was teaching, be it one-on-one with his trainees or in front of a large audience come to learn during one of his courses. What always impressed me was his unbridled and infectious enthusiasm, especially for the interesting tracing. This could be intimidating to some of his students initially, but it was guaranteed to get them involved in the issue at hand.

It is with considerable humility that I have tried to capture some of the deductive thinking and problem solving that he was so good at. Rarely at a loss for words and very quick, Mark would be a very difficult act to follow for most of us. Hopefully, a methodical approach using what I call the “tools” of analysis can bring us a little closer to his excellence.

I have included one of my favorite pictures of Mark during happy times with his wife Joan, his lifelong best friend and soulmate.
