A preliminary study on normal electrocardiographic parameters of ostriches (Struthio camelus)
Electrocardiograms were taken from 100 normal healthy male and female ostriches which were 1 to 15 months old using a base apex lead. The heart rate of those less than 3 months old ranged from 107 to 250 beats per minute with a mean of 171.47+9.03 and that of ostriches of more than 3 months old rang...
