Abstract
This paper presents electrocardiographic values in 25 Holstein calves using the standard bipolar limbs leads (I, II and III), augmented unipolar limb leads (avL, avR and avF) and a bipolar chest lead (V10). Two groups with different ages were compared (newborn - 18 to 72 hours and calves - 27 to 33 days old). It was concluded that no differences between age groups in P, Q, R, S and T waves, in the PR, QRS, QT and ST intervals and in axis orientation were observed.Keywords
