电击伤是由电流通过机体组织时电能转化为热能引起的。决定电击伤种类和严重程度的因素包括传输能量的大小、电压、电流阻力、电流类型、与电源接触的持续时间和电流通路。电击的受害者可能遭受广泛多样的损伤,低强度电流可引起短暂的不适感,接触高电压或高电流可引起瞬时的心脏骤停。 Electrical injuries are caused by the electrical energy being converted into heat energy by the current flowing through the body’s tissues. Factors that determine the type and severity of electrical injury include the size of the transmitted energy, voltage, current drag, type of current, duration of contact with the power supply, and current path. Victims of electric shocks can suffer a wide variety of injuries, low-intensity currents can cause brief discomfort, and high-voltage or high-current exposure can cause transient cardiac arrest.
