Electrocardiographic studies using bipolar base apex lead-i in apparently healthy goats

A study was conducted to evaluate the cardiothoracic parameters in 12 apparently healthy goats. They were divided into two groups (Gr-I: 3–6 months-old and 11.83±0.70 kg body weight; Gr-II: 6–12 months-old and 25.67±1.73 kg body weight). Electrocardiogram (ECG) was recorded using bipolar base apex lead using limb lead-I in standing position in calm goats without any sedation. Significant (P<0.05) negative correlation was found in the value of heart rate with body weight and age of the goats. Amplitude of P wave showed positive correlation with both age and body weight, R and T wave with body weight and R wave showed significant (P<0.05) positive correlation with age while other parameters of amplitude were negatively correlated with both age and body weight. Significant (P<0.05) positive correlations with both age and body weight were observed in duration in QRS complex and R-R interval. The baseline data of cardiothoracic parameters and their correlation with age and body weight appears to be helpful in diagnosing various cardiothoracic abnormalities in goats.
