I controlled tests (which obviously were not well enough controlled) 12
volts DC applied across the chest of a volunteer caused death. This would be
exceptional but is obviously possible. DC and AC produce somewhat different
results but the safe conclusion is that any HV shocker COULD cause death.
YMMV.
