Book

ABSTRACT

This title provides ECG reference material in a fast and easy to use format. It is a wonderful reference for ECG data and provides samples of actual small animal ECG results with treatment recommendations. Easy to follow explanations of how to perform and interpret electrocardiograms are included. This presentation includes a brief review of physiology, technique and equipment, and interpretation of common electrocardiographic abnormalities. The friendly, non-textbook approach along with the use of helpful symbols, tips and examples, aid practitioners in learning to focus on the most elusive of features. A helpful drug formulary is provided in the appendix. The interpretation material is extremely helpful for the small animal practitioner, and the simple yet in-depth explanations are wonderful for the small animal technician. An ECG ruler which can be purchased separately allows the veterinarian to quickly determine heart rates and measure intervals easily and accurately. This is an excellent book for practitioners to keep by the ECG unit to insure that they do not miss even the slightest indication of cardiac irregularity. Published by Teton New Media in the USA and distributed by Manson Publishing outside of North America.
