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] Very small currents may be imperceptible or only produce a light ...
Electrocution is death or severe injury caused by electric shock from electric current passing through the body. The word is derived from "electro" and "execution", but it is also used for accidental death. [1][2] The term "electrocution" was coined in 1889 in the US just before the first use of the electric chair and originally referred to ...
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]
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 ...
An implantable cardioverter-defibrillator (ICD) is a battery-powered device that monitors electrical activity in the heart, and when an arrhythmia is detected, can deliver an electrical shock to terminate the abnormal rhythm. ICDs are used to prevent sudden cardiac death (SCD) in those who have survived a prior episode of sudden cardiac arrest ...
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. [1][2] Initial symptoms of shock may include weakness, fast heart rate, fast breathing, sweating, anxiety, and increased thirst. [1] This may be followed by confusion, unconsciousness, or cardiac arrest, as complications ...
Electroconvulsive therapy (ECT) or electroshock therapy (EST) is a psychiatric treatment during which a generalized seizure (without muscular convulsions) is electrically induced to manage refractory mental disorders. [1] Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 milliamperes of ...
Lightning injuries are injuries caused by a lightning strike. [4] Initial symptoms may include heart asystole and respiratory arrest. [1] While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. [1] Other symptoms may include burns and blunt injuries. [1]
