The prisoner is fastened into the chair by the wrist’s waist and ankles. They will usually be blindfolded, and one of them, of course, loses control of bodily functions. Then, the guard performed the process of placing the straps and belts. Next, a metal headpiece was put on the prisoner’s head, which also had a wet sponge underneath. When everyone was out of the room, the open electrical system was turned on. The first current was applied for 15 seconds, discharging up to 2000 volts, which should stop the heart. The second current was applied for 20 seconds to damage all the remaining organs that might be working. At this point, the prisoner’s body will be convulsed. Electrocution leads to paralysis of the brain’s respiratory centers and stops the muscles pumping the heart. Sometimes the body will become very hot, even burnt, and the eyeballs protrude. The facial muscles will also contort, as you can well imagine.
