Josephson worked closely over the years with European cardiac electrophysiology pioneer Hein Wellens, chief of cardiology emeritus at the University of Limburg in Maastricht, Netherlands. For over 30 years, they coached together at high-yield "How to Approach Complex Arrhythmias" course for cardiologists and EP fellows. In the 2000s, they initiated an advanced course "Intracardiac Unknowns" which was attended by most electrophysiology trainees in the USA for over 10 years.

Josephson has published over 400 original journal articles and 200 book chapters and reviews and is the author of the textbook of clinical cardiac electrophysiology, Clinical Cardiac Electrophysiology: Techniques and Interpretations. First published in 1979, the book has run to six editions.

Mark E. Josephson (1943-2017) was an American cardiologist and writer, who was in the 1970s one of the American pioneers of the medical cardiology subspecialty of cardiac electrophysiology. His book titled Clinical Cardiac Electrophysiology: Techniques and Interpretations is widely acknowledged as the definitive treatment of the discipline. He served as Herman Dana Professor of Medicine at Harvard Medical School, director of the Harvard-Thorndike Electrophysiology Institute and Arrhythmia Service and the chief of cardiology at Harvard University's Beth Israel Deaconess Medical Center in Boston.
