Electrocardiographic parameters of Markhoz goat using base apex lead and six standard limb leads

ABSTRACT

Electrocardiographic study of 50 healthy Markhoz goats ranging from less than 1 to more than 3 years in age was carried out. The heart rate varied from 99 to 123 beats/min with a mean of 110 beats/min. There was a significant difference between the heart rate of goats in 3 age groups [[P<0.05]. The mean duration of P and T waves and QT interval in base apex lead, QRS wave in lead I, P-R and PQ interval in aVF lead were higher and duration of QRS and T waves in aVR lead, P wave in lead III, PQ and P-R intervals in lead II and QT interval in aVR lead were lower than those in the other leads. The mean duration of QT interval had significant changes with age [P<0.05]
