ECG is a simple diagnostic tool which provides a wealth of clinically useful information. It is rather timely, after the publication of the book Atlas of Electrocardiography, to publish this work, ECG Self-Study Book, as a companion to it. In this self-study book, I compiled over 400 practice tracings representing nearly all clinical entities we commonly encounter. Each page has an ECG tracing for you to analyze. Some have multiple choice questions and some require drawing a ladder diagram. Answers or diagnoses and discussions are in the bottom of the tracing for you to compare with yours. Salient features of the tracing, the logic behind the ECG findings, and the clinical relevance of the findings are emphasized. 

The book is divided into 30 sections, each section containing 12 cases. The idea is that if one studies one section each day, one would finish the book in 30 days. Of course, one does not have to follow the schedule. 

It is hoped that, after practicing on these tracings, one would feel more comfortable in dealing with ECG. Not only does it becomes easier to pick up subtle findings but also understand why the ECG findings manifest the way they do, what is happening to the patient, and what to do about it. In so doing, one would be better prepared to deliver better patient care, which, after all, is what matters. In so doing, the patient care becomes more enjoyable.
