title: [Atypical hypoxic changes in the T wave].
abstract: Three patients with clinical diagnosis of myocardial infarction are described, whose cardiograms are characterized by a transitory positivation of the negative T-waves. The confrontation of those changes with the clinical picture reveals that the transitory positivation of the T-wave coincides with the clinical and paraclinical signs of intensification of the myocardial hypoxia (pain, collapse, enzyme positivation). The possible electrophysiological mechanisms are discussed that could explain the transitory positivation of the negative T-waves, as a manifestation of the intensified ischemia.
