Praise for the Second Edition:. ""This is an excellent workbook for students or healthcare professionals who are just beginning to interpret 12-lead EKGs. The book covers what is expected, but the manner in which it presents the material brings much clarity to the topic."". -- Doody''s Medical Reviews. This handy, step-by-step guide for medical and nursing students and novice practitioners delivers ample information for confidently interpreting 12-lead EKGS. It goes beyond the many EKG books that rely on rote memorization by actively engaging students in the learning process. The guide fosters.
