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 (PT 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).
