![]() Still larger currents result in tissue damage and may trigger ventricular fibrillation or cardiac arrest.

A shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. Very small currents may be imperceptible or produce a light tingling sensation. The injury depends on the density of the current, tissue resistance and duration of contact. The slight branching redness (sometimes called a Lichtenberg figure) travelling up the leg was caused by the effects of current.īurns, rhabdomyolysis, cardiac arrest, bone fractures Įlectrical injury is a physiological reaction caused by electric current passing through the body.
