Abstract

The objective of this study was to establish the standard electrocardiographic (ECG) values for six dog breeds and to evaluate the influence of gender and age on various ECG parameters. Labrador Retrievers (22), Pomeranians (11), mongrels (13), German Shepherds (10), Golden Retrievers (13) and Gaddi dogs (9) were included in the study. Dogs were positioned in right lateral recumbency without the use of any chemical restraint and six-lead ECGs were recorded, comprising three bipolar standard limb leads (I, II and III) and three augmented unipolar limb leads (aVR, aVL and aVF). Parameters like amplitude, duration of P-wave, QRS complex, PR interval, QT interval, mean electrical axis and heart rate were measured for each recording. Amplitude and durations of ECG waves across all six leads were not statistically affected by gender or age. P(mV) was significantly greater in Pomeranians as compared to mongrels whereas, Gaddi breed showed significantly greater Q(mV) as compared to Golden Retrievers.
