electrocardiographic parameters of markhoz goat using base apex lead and six standard limb leads

electrocardiographic study of 50 healthy markhoz goats ranging from less than 1 to more than 3 years inage was carried out. the heart rate varied from 99 to 123 beats/min with a mean of 110 beats/min. there wasa 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 higherand duration of qrs and t waves in avr lead, p wave in lead iii, pq and p-r intervals in lead ii and qtinterval in avr lead were lower than those in the other leads. the mean duration of qt interval hadsignificant changes with age (p
