Shortly thereafter, in 1892, the term was used in Science to refer generically to death or injury caused by electricity. Factors in lethality of electric shock
The lethality of an electric shock is dependent on several variables:

Current. The higher the current, the more likely it is lethal. Since current is proportional to voltage when resistance is fixed (ohms law), high voltage is an indirect risk for producing higher currents. Duration. The longer the duration, the more likely it is lethal—safety switches may limit time of current flow
Pathway. If current flows through the heart muscle, it is more likely to be lethal. High voltage (over about 600 volts). In addition to greater current flow, high voltage may cause dielectric breakdown at the skin, thus lowering skin resistance and allowing further increased current flow. Medical implants. Artificial cardiac pacemakers or implantable cardioverter-defibrillators (ICD) are sensitive to very small currents. Pre-existing medical condition. Age and sex.Other issues affecting lethality are frequency, which is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but does not penetrate the body far enough to cause cardiac arrest (see electrosurgery). Also important is the pathway: if the current passes through the chest or head, there is an increased chance of death. From a main circuit or power distribution panel the damage is more likely to be internal, leading to cardiac arrest.
A "flare" is a spreading area of redness or flush. It is the second reaction in the triple response to injury and is due to dilatation of the arteriole. When this flare occurs around the ankle, it is called an ankle flare. The condition is also known as a malleolar flare, in reference to the malleolus, the bony prominence on each side of the ankle. Ankle flares are often caused by venous ulcer, due to deep vein thrombosis or varicose veins. It is considered to be an early sign of advanced venous disease. Treatment involves management of the underlying condition, along with supportive care. See also
