Electrocardiographic parameters of Markhoz goat using base apex lead and six standard limb leads %K Electrocardiography %K Goat %K Markhoz breed %R 10.22099/ijvr.2013.1688 %X 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<0.05). %U https://ijvr.shirazu.ac.ir/article_1688_39f60046b36ff569c19b6ca5ccdc56f7.pdf
