Electrocardiography of the dog and cat. Diagnosis of arrhythmias. II Edition

"The main objective of this book is to give both clinical and theoretical information to interpret simple and complex electrocardiograms in dogs and cats. Detailed description of normal rhythm variations and arrhythmias is provided to meet the readers’ needs whether they are just beginners or experts."

The combined and varied experiences of the authors give texture to the review of the literature, and the approach to electrocardiogram interpretation in the dog and cat. Key 14 detailed chapters emphasize important key points in the assessment of the electrocardiogram, including vectors of depolarization and repolarization, relationship of cardiac structure to electrophysiology, detailed steps for electrocardiographic interpretation, hemodynamic consequences of rhythm disorders, new understanding of supraventricular arrhythmias, etiologies of ventricular arrhythmias, parameters to assess risk and need for treatment, and description of cardiovascular reflexes. More than 300 beautiful illustrations and electrocardiograms to stimulate visual learning coupled with easy to consult boxes of key points for the rapid diagnosis on a day-to-day basis. At the end of the book, to illustrate the step-by-step approach to the electrocardiogram, additional tracings with an accompanying interpretation give the reader the assurance of accomplishment from reading this book. This book is a must-have reference for those learning the basics of electrocardiography and those who face the challenge of interpreting the most complex arrhythmias in veterinary medicine. "This Manual of Dog and Cat Cardiology is a complete and updated text on current knowledge in the field of veterinary cardiology. The work was designed and implemented with the intention of providing a critical analysis of the topics covered and to convey to the reader a point of view as much as possible based on scientific evidence. In recent years, the new diagnostic methods have allowed us to broaden the analysis of the various branches of cardiology of pets with particular regard to the etiological and therapeutic aspects" -- OCLC This book is a must-have reference for those learning the basics of electrocardiography and those who face the challenge of interpreting the most complex arrhythmia in veterinary medicine.
