Electrocardiographic Signs of Ischemia

  Ischemic changes, depending on localization of Myocardium Ischemia and Infarction see below. They involve changes in T-wave morphology, including inversion, tenting, or both. More obvious ischemia may be seen in the form of progressive ST-segment depression. Down-sloping and horizontal ST depressions are of greater specificity for ischemia than is up-sloping depression.
