Exercise in electrocardiographic interpretation.

The response of the heart to disease can be detected by assessing myocardial electrical activity. The electrocardiograph is a useful diagnostic tool which is widely available to the veterinary clinician. However, interpretation of the tracing often requires considerable experience.Regularly, electrocardiograms (ECG) of clinical cases will appear in this column. Each tracing will be preceeded by the history and the pertinent ancillary data. Interpretation and discussion of the ECG will follow. The purpose of this column is to present clinicians with examples of common electrocardiographic abnormalities.
