Macroshock (mak´ro-shok″) There is an inconsistency in the medical world as to the definition of macroshock. Some sources claim any electrical current that passes through the skin and into the body that is larger than 10mA is considered a macroshock, other sources claim that it must pass through the trunk, and yet still other sources claim it must pass through the heart. This is the most common type of electrocution. There is little inconsistency as to the sources of macroshock. The term is used regularly in electrophysiology and bioengineering.

See below for 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]
