Useful information in easy to read format
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!

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!
