EKGs are difficult and I still don’t understand
Format: Paperback
Hey I’m in nursing school and I bought this… it’s not the pocket size, it’s actually a full size book. It brought tears to my eyes many times. I have no idea what a 3rd degree block is. Hopefully you can learn and be a good nurse! EKGs are for the doctors to read. So don’t be too hard on yourself. But you should probably know what normal sinus rhythm looks like… 👍🏼

My teacher thinks some of the ekgs are wrong
Format: Paperback
Can anyone put me in contact with the author of this book? My ekg/cardiology teacher is slandering her name and saying some of the rhythms she has in this book are wrong. Really upsets me because he is only a nurse and teaching a pre paramedic course. Doctors and cardiologist were the ones who cited this book. The rhythms are correct, my teacher just wants to think he is smarter than everyone else when it comes to cardiology. Otherwise I love this book and very helpful.

Excellent Book
Format: Paperback
As a nurse I struggle sometimes with rhythm recognition for some of the more complicated ones. This book is easy to read with many practice strips to help you comprehend even the complex details. Would highly recommend to anyone who needs to learn EKGs or brush up on their rhythm recognition skills. Great book!

Thin pages
Format: Paperback
I purchased this book a couple months back but just started school so I just started using this book and come to realize that these pages are way too thin, you can literally see the words of the following pages and the ink on the pages started to smear where ever I touches, I can't even highlight anything or else the other side of the page would be a mess.
