An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
Modern shock voltage is given for a shorter duration of 0.5 milliseconds where conventional brief pulse is 1.5 milliseconds. [ 31 ] In a review from 2022 of neuroimaging studies based on a global data collaboration ECT was suggested to work via a temporary disruption of neural circuits followed by augmented neuroplasticity and rewiring.
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. [1] [2] Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. [3]
The term "electrocution" was coined in 1889 in the US just before the first use of the electric chair and originally referred to only electrical execution and not other electrical deaths. However, since no English word was available for non-judicial deaths due to electric shock, the word "electrocution" eventually took over as a description of ...
Shock therapy describes a set of techniques used in psychiatry to treat depressive disorder or other mental illnesses. It covers multiple forms, such as inducing seizures or other extreme brain states, or acting as a painful method of aversive conditioning .
By this definition, the magnitude of the current itself (in amperes) is the most important factor. In general, the greater the current, the more dangerous a shock is and the more likely it is to be lethal. Therefore, a high-voltage, low-current shock is not dangerous, but a low-voltage, high-current shock may cause significant harm or death.

Electric shock drowning is a term used in the US to describe a cause of death that occurs when swimmers are exposed to electric currents in the water. In some cases the shock itself is fatal, since the person will suffocate when their diaphragm is paralyzed, while in others it incapacitates the swimmer causing them to drown.
