This is a book of 100 full 12-lead ECGs displayed on the upper part of a double-page spread with, below, notes and illustrations about the particular features of the ECG that are of importance, and a clinical comment on the case along with a list of the common causes of the problem. Thus the book provides in itself a collection of full 12-lead ECGs of a wide range of common clinical problems encountered in casualty, ordered in the way that a fledgling ECG mind might place them. All the ECGs are reproduced as real traces and are of normal size. Examples of variation in the clinical conditions are also included. The book carries on from simpler ECG books and provides a greater depth of experience in ECG training.
