The "Pocket Guide to Electrocardiography" has been expanded and updated to provide nurses and students with up-to-date material on arrhythmia detection and identification. The book's consistent format and comprehensive presentation of material makes it an easy-to-use reference for nurses and students who wish to enhance or refresh their understanding of electrocardiography. As in the first two editions, each section has a standard organization and includes a brief overview of anatomy and physiology ECG characteristics, pathophysiology, nursing implications, variations and differential diagnosis, and treatment. Also, each chapter is preceded by an illustration of the heart with arrythmia sites anatomically highlighted in a second colour.
