Summary

  • May be caused by exposure to high- or low-voltage electricity or lightning. Tasers may also cause a mild electrical injury.
  • Recognition of arrhythmias is an essential element of the initial evaluation of electrical injury.
  • Most electrical shocks cause no injury.
  • May cause electrical and thermal burns, and secondary injuries due to a fall, severe tetany, or the force of electrical blast.
  • Survivors of high-voltage electrical injury or lightning strikes can have long-term sequelae, and regular follow-up is essential.
