This book explains EP in plain English! I think it is in a class by itself." EP Technician, Galichia Heart Hospital, Wichita, KS, USA "It gives a good understanding of EP without getting too technical and complex in the explanations. It accomplishes a major task of "demystifying" the field of EP. It not only addresses the needs of non technical EP Personnel, but also provides a precise overview of EP for general review." Cardiac NP, St. Jude's Medical Center.
