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.
