The reader's rapid assimilation of medical concepts is the key to the continuing success of this best-selling book. A caption explains the concept illustrated on each page, and a few simple sentences reinforce the concept with interactive (programmed) learning, which links to the following page. Dr Dubin's light and entertaining style, known world-wide, makes learning enjoyable. Practice twelve-lead tracings at the end establish self-confidence, and summarised reference sheets with examples (designed to be copied) provide an excellent review.
