title: [Regarding so-called ischemia, injury and necrosis].
abstract: The authors emphasize that "necrosis", "injury" and "ischemia" are terms employed with different meanings by electrocardiographists, hemodynamists and pathologists. In the electrocardiographic field, they correspond respectively to complete diastolic depolarization, partial diastolic depolarization and slow repolarization: the three key concepts of the electrophysiopathology. The terms as used in electropathology reflect functional changes based on metabolic and electrolytic conditions which must be explored by means of such functional methods as electrocardiography. Therefore the electrical meanings of the terms "ischemia", "injury" and "necrosis" do not correspond to those understood by hemodynamists and pathologists. The electrophysiopathologic terminology should always be used to indicate functional phenomenon which originates at the cellular level in order to avoid diagnostic pitfalls and mistakes.
