A master practitioner illustrates with 185 electrocardiograms a new scientific approach to the art of EKG intrepretation. Moving beyond the traditional practice of many books that stress technical skill and pattern recognition, Dr. Blake demonstrates in detail how tracings may be interpeted with consistency and medical rigor to distinguish normal and abnormal EKG patterns. Each tracing is illuminated by a full description of its findings and a detailed clinical explanation of how to intrepet it. Published in both hardcover and paperback this book will be used by medical students in preparation for their exams as well as by practicing physicians who want to develop a scientifically-based approach to reading EKGs.
