Correlation between 25 element contents in mane hair in riding horses and atrioventricular block.
The influence of atrioventricular block (AV-block) on the trace elemental status in a horse hair was studied. The particle-induced X-ray emission (PIXE) method has provided a reliable, rapid, easy, and relatively inexpensive diagnostic method. Twenty-five elements (Al, Br, Ca, Cl, Co, Cu, Cr, Fe, Hg, K, Mg, Mn, Na, Nb, Ni, P, Pb, Rb, S, Se, Si, Sr, Ti, Y, and Zn) in mane hair and serum were measured by the PIXE method. A horse hair with first- and second-degree AV-block contained significantly greater amounts of Br, Ca, Sr, and Zn than those of horses without electrocardiographic abnormalities, whereas there was no significant differences in the elemental contents of the serum of the both groups. Those results in contents of a horse hair suggest that the evaluation of the degree of ionic imbalance by this method might be used to predict the susceptibility of a horse to heart disease much before symptoms appear.
