Key Features

  • Thumb tabs and lay-flat spiral binding make it easy to use anywhere, and the small size fits easily into a lab coat pocket.
  • Unique Flip and See section at the end of the book allows you to see each rhythm side-by-side with a normal ECG rhythm, and a written walkthrough explains the important differences between the rhythms.
  • Conversational language and clear illustrations and cartoons make the information easily accessible and understandable – as well as easy to remember and fun to learn.
  • Includes Cohn’s Pocket Guide for ECG Interpretation, a plastic heart rate ruler that’s useful for both students and practitioners as an aid in rhythm interpretation.
