    Summary

    This study analyzed electrocardiographic (ECG) findings in dogs, revealing distinct Q and T wave patterns in standard versus chest leads. Results highlight the importance of incorporating chest leads for comprehensive canine ECG analysis.

    Area of Science:

    • Veterinary Cardiology
    • Comparative Electrocardiography

    Context:

    • Electrocardiography (ECG) is crucial for assessing cardiac health in animals.
    • Standard ECG leads may not capture all relevant cardiac electrical activity in canine subjects.
    • Understanding lead-specific ECG variations is essential for accurate interpretation.

    Purpose:

    • To document electrocardiographic findings in unanesthetized dogs under specific positioning.
    • To compare Q and T wave characteristics between standard and chest leads.
    • To evaluate the necessity of using chest leads in canine electrocardiography.

    Summary:

    • Electrocardiographic (ECG) data were collected from 70 unanesthetized dogs adapted to their environment and positioned on their right side.
    • Q waves appeared in over half of standard leads but were absent in chest leads.
    • T waves were frequently negative in standard leads and positive in chest leads, with individual ECG patterns remaining consistent.

    Impact:

    • Findings suggest that standard ECG leads alone may be insufficient for complete cardiac assessment in dogs.
    • The study underscores the value of integrating chest leads with standard leads for enhanced diagnostic accuracy.
    • This research contributes to improved methodologies in veterinary cardiology and canine ECG interpretation.
