ABSTRACT
Chalmeh
A, Pourjafar M, Heidari SM,
Sanati AR, Shahbazi A, Badkobeh M, Bagheri MH., Base apex electrocardiography of goats by
age, Onl J Vet Res., 29 (2): 94-99, 2025. We recorded bipolar base apex lead through limbs of 13 fifteen day,
18 two month, 19 six month, ten year, 22 three year, 16 five year and eleven 7 year-old
Nadji goats. The electrocardiograms were recorded on
a bipolar base apex lead, using limb lead I. Compared with 7 year old animals, in
15 day old goats P wave was 40%, P amplitude 19%, PR 42%, RR 47% and S intervals
were 52% lower (P < 0.05). However we found no difference with S amplitudes
or durations. Results suggest aging affects electrocardiograms due to increased
dimensions of heart chambers and walls.
