Podrid's Real-World ECGs:A Master's Approach to the Art and Practice of Clinical ECG Interpretation. Volume 1, The Basics.
There are many review books for ECG interpretation, but few are as enjoyable to read and study as this one. It does an excellent job of presenting electrocardiograms, interesting clinical vignettes, and important clinical questions in a clean and concise format. The strength of this book is the systematic review of every example electrocardiogram. --Doody(February 2013)4 Star Review
