Paramedic before 12 leads
This was easy to understand and I have read other books that you read 3 or 4 chapters and still know nothing about reading 12leads. I don't have time to spend a week or more trying to learn to read them. I can now feel confident in STEMIs diagnosis!

I am biased here because I love this author.
Dr. Caputti is very detailed in her information while dispersing it in an organized and easy to follow manner. I would recommend anything she publishes as well any conferences at which she speaks to inform RN/PNs of test strategies and how professionals think through patient scenarios.
