Thank you :-). I really appreciate your detailed and informative response. I had already ordered a few books by the time I read it though. The book you mentioned sounds wonderful! I had bought two books from amazon based on overall ratings, comments, and recommendations:
ECG Workout: Exercises in Arrhythmia Interpretation (Huff, ECG Workout)
Huff RN CCRN, Jane (This book has a ton of exercises as well as explanations)
Rapid Interpretation of EKG's, Sixth Edition
Dubin, Dale (Has 4.5 rating from over 400 reviews. Is recommended by all healthcare professionals due to ease of reading)
I had also bought Kathy White's fast facts for critical care as a reference book to have with me during my job. If the two EKG books I bought do not suite me, I will definitely purchase the one you recommended.
