As a new 1 year paramedic, this book was a lifesaver. This book encompasses weeks of teaching into an easy 45-minute read. I am more confident in my ekg assessment and ACLS treatments while not being confused by classic medical book jargon. I 100% recommend this book for new and student paramedic or even those who want a refresher from school. You can even supplement with further ecg strip practice on your own. Thank you!!

Made the material understandable

I was definitely struggling with EKGs until I read this book. I felt like it was able to dumb it down enough for me to understand. Definitely helped

Excellent real-world reference information that is easy to pick up and read small sections when you have time. First well in my bag and not bulky. Gives you just what you need to interpret EKGs quickly!
