With over 200 traces to test your knowledge, this book is a first class learning tool for emergency physicians. Basic student-level knowledge of ECGs is assumed, so the reader can move directly to learning about the more complex traces that occur in the emergency department. The level of difficulty is stratified into two sections for specialists in training and specialist emergency physicians. A minimum amount of information is given beneath each trace, as if in the real situation. The full clinical description is printed in a separate section to avoid the temptation of “looking”. Accompanied by learning points, and with the cases presented randomly, this book provides a rich source of information on the interpretation of ECGs – a core skill for all emergency department staff.
