Description
Book SynopsisLife-Threatening Cardiac Emergencies for the Small Animal Practitioneroffers a quick reference to recognizing and treating common cardiac arrhythmias and emergent cardiac conditions in canine and feline patients, designed for fast access during an emergency.
- Offers quick and easy access to key information for diagnosing and managing arrhythmias and cardiac conditions in dogs and cats
- Designed for ease of use in the fast-paced emergency setting
- Presents clear, reproducible ECGs, radiographs, and echocardiograms for reference and comparison
- Part of the Rapid Reference series providing small animal practitioners with ideal quick references for patient-side guidance
Trade Review"Life-Threatening Cardiac Emergencies for the Small Animal Practitioner is a quick reference for some of the most common small animal cardiac emergencies that private practitioners encounter. The text describes a basic approach to ECG interpretation and provides a concise evaluation and review of many common cardiac arrhythmias categorized by heart rate as well as some commonly diagnosed cardiac conditions. The images presented are clear JAVMA • Vol 250 • No. 12 • June 15, 2017 1405 and easy to follow and understand with the captions provided. This book is not intended to provide readers with a detailed explanation of the electrophysiology and potential variations of arrhythmias or complete review of cardiac pathophysiology. The information presented is basic and geared more for quick reference by primary care veterinarians rather than cardiologists and is comprehensive in this regard. Overall, it is a concise, well-organized basic reference guide for common cardiac emergencies of small animals"
