From what little I've been taught about electrical shocks and resuscitation
I seem to remember that 120 was actually "more lethal" than 240 ... something
to do with fibrillation (from a 120 shock) versus complete stoppage of the
heart with a 240 volt shock.  (It is harder to resuscitate an individual
in fibrillation(?)). 

I would suspect this all this depends on the current through the heart
muscle.  Perhaps someone applied Ohm's law with some practical  values
for body resistance, etc.
