Abstract
Aim:
The present study has been conducted to evaluate the variation
in electrocardiogram (ECG) parameters among different trained
breeds of dogs (viz.
Labrador, German Shepherd, and Golden Retriever) used for
security reasons.
Materials and Methods:
The ECG was recorded by single channel ECG at a paper speed of
25 mm/s and calibration of 10 mm=1 mV. The recordings were taken
from all the standard bipolar limb leads (Lead-I, II, and III)
and unipolar augmented limb leads (Lead-aVR, aVL, and aVF).
Results:
Heart rate was found to be highest in Labrador and lowest in
German Shepherd. P-wave duration was maximum in Golden Retriever
breed and lowest in Labrador. Maximum amplitude of P-wave was
found in Labrador followed by German Shepherd and Golden
Retriever. There was significantly (p<0.05) higher values of PR
interval in German Shepherd compared to other breeds. The
variation in QRS duration, ST segment duration, T-wave duration,
and T-wave amplitude was found to be non-significant among
breeds. Inverted T-waves were most common in Golden Retriever
and German Shepherd, whereas positive T-waves were found in
Labrador. There was significant (p<0.05) variation in mean
electrical axis of QRS complex among different breeds and it
ranges from +60° to +80°.
Conclusion:
The present study provides the reference values for different
ECG parameters to monitor the cardiac health status among
Labrador, German Shepherd, and Golden Retriever breeds.
Keywords:
dog, electrocardiogram, mean electrical axis.
