Interpretation of the Normal ECG
Correct interpretation of the ECG
requires a systematic approach. Therefore it is recommended that you think of
certain questions each time you read any ECG:
What is the ventricular rate? Is it
reasonable for the animal's species, age and the situation?
Are all of the ventricular complexes of the same configuration?
Are they normal for the species and the lead used? (use

Are all QRS complexes preceded by P waves? Are all P waves
followed by QRS complexes?
Are all of the P waves of the same configuration? Are they normal
for the species and the heart rate?
