Yes, and they did it entirely wrong. The heart model they used was in no way shape or form representative of any real world scenario, and the BODY model they used did not take into account anything related to the blood, which is quite salty, and the main part of what kills in electrocution scenarios.
It was in now way representative of how a shock between two extremities would occur, NOR was it representative of how a current would flow through a body in a tub of water.
Yeah, and they got it 100% wrong, IMNSHO.
