Macroshock

Macroshock (mak´ro-shok″) is a medical term for the effects of body exposition to electrical current, which can lead to electrocution and death. It is used regularly in electrophysiology and bioengineering[citation needed].

Definitions of macroshock in the medical world are inconsistent. Some sources[who?] use the term for any electrical current in excess of 10 mA passing through the skin and into the body, others[who?] require the current to pass through the trunk or the heart.

There is little consistency provided to accurately define the term macroshock. See examples:

1 A strong electric shock resulting from current that has passed through the trunk, with contact to the source through intact skin.[1]

2 This is defined as the passage of current from one part of the body to another, especially from arm to arm and therefore through the heart. The current is the most important factor. (A high-voltage low-current shock is not dangerous.) [2]

3 During macroshock, current passes between two different skin areas....[3]

Sources of Macroshock[edit]

  • Poorly designed, or malfunctioning electrophysiology equipment
  • Lightning
  • Melted power cords
