This is my favorite ECG book.
Include brief discussions about the diseases causing the ECG abnormalities, sometimes with treatment, and handy boxes with summaries of the key points. It’s beautifully illustrated with many ECG samples of great quality. The final chapters come with differential diagnosis, reviews and exercises, which are very useful.
In my opinion, this is a well balanced text, not trying to be too simplistic, neither too complex, what is a hard achievement to get in this subject.
Could treat better some important topics - for example, the localization of the MI is given in a rather confusing way and is not well summarized - but in general, is a really great book, very complete and worth the time and effort of studying it thorough.
After reading this carefully, you will never see an ECG the same way.
