If you are a cardiologist or have a photographic memory,you may not need Dr.Foster’s new book.But,for the rest of us on the front lines of emergency care,it is a valuable resource that you will want to have by your side at work. I have had the first edition of this book by my station in the emergency department for ten years now.I use it everyday for teaching house staff and often turn to it for reference myself. For those of us without perfect memories,Dr.Foster’s clinical approach is ideal. He has the knack of making the complex simple. He does not expect the reader to memorize every squiggle on the page; instead he inspires understanding by giving readers the tools they need to comprehend why ECGs look the way they do.When a resident comes to me with an ECG,I do not have to spend ten minutes delivering a confusing explanation.I just open Dr.Foster’s book to the right page and hand it to the resident for review. The book is organized so that you can turn to the relevant chapter and instantly know what the differential diagnosis might be.His selection of case studies covers the vast majority of the ECGs you will be called on to read in any sort of emergent situation; anything else can wait for the cardiologist.
