Renosteinke raises some good points. I once heard a very interesting presentation about electric shocks by a neuropharamacologist, who held that 120V was statistically the most dangerous voltage because of the frequency of inadvertent contact with a live circuit—either by “trained” or “untrained” persons. [277V contact is more serious, but has less frequent occurrence.]

The presenter explained that a very common aftereffect is <i>delayed muscle atrophy.<i> As I recall, healthy nerve tissue normally regenerates itself, but electric shock halts that regeneration process. This leads to the inability to fully use the limb on the order of six months to years after the initial injury.
