This simple, innovative method for understanding and interpreting 3-lead ECG readings is now revised and updated for a 2nd edition. Complex concepts are presented in a fun, engaging format that uses humor, cartoons, and personalstories to walk the reader through the entire ECG process - from finding a heart beat, to taking an electrocardiogram, to interpreting the patient's heart rhythm, and understanding how to treat the patient. Commonly asked questions and answers are interspersed throughout the text to help clarify concepts and procedures. Building on basic concepts presented in the first part of the book, the second part teaches readers how to interpret 25 common dysrhythmias and provides the description and treatment of each. The sample ECG strips can be studied as a whole, or separated at a perforation to create over 260 different ECG rhythms.
