This is a complete textbook of electrocardiography written and illustrated expressly for non-cardiologists who need to understand ECG equipment, procedures, and terminology as well as how to produce, read, and accurately interpret ECG tracings. The book is built around clear, instructive diagrams and definitive, compact accompanying text presented in 28 chapters that begin with basic cardiac anatomy and physiology and the electrical activity of the heart, then continuing through a complete course on electrocardiography leading to the concluding chapter describing a systematic way of reading electrocardiograms.
