Editing Electrophysiology (section)

====Electrographic modalities by body part====

Electrophysiological recording in general is sometimes called electrography (from ''[[wikt:electro-#Prefix|electro-]]'' + ''[[wikt:-graphy#Suffix|-graphy]]'', "electrical recording"), with the record thus produced being an electrogram. However, the word ''electrography'' has other [[word sense|senses]] (including [[Kirlian photography|electrophotography]]), and the specific types of electrophysiological recording are usually called by specific names, constructed on the pattern of ''electro-'' + [body part [[classical compound|combining form]]] + ''-graphy'' (abbreviation ExG). Relatedly, the word ''electrogram'' (not being needed for those other [[word sense|senses]]) often carries the specific meaning of intracardiac electrogram, which is like an electrocardiogram but with some invasive leads (inside the heart) rather than only noninvasive leads (on the skin). Electrophysiological recording for clinical [[medical diagnosis|diagnostic]] purposes is included within the category of [[electrodiagnostic testing]]. The various "ExG" modes are as follows:
