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.
