Higher levels of shock can cause fibrillation of the heart which is almost always fatal. Electric shock can also cause burning of the skin at the point of contact. The following table lists the health effects of exposure to electric currents. This is caused by the passage through the heart of current which disturbs the regular electrical impulses within the heart itself. This results in an oscillating condition rather than the normal regular beating.
Blood flow is thus impaired and death follows from lack of oxygen to the brain.
