[Ischemic pseudo-normalization of T waves and ST segment].
The development of acute myocardial ischaemia in a territory with baseline repolarization abnormalities can be reflected by transient pseudo-normalisation of the T wave and/or ST segment. These repolarization abnormalities can occur spontaneously, during a stress test or during of an isoproterenol test. Clinicians should be familiar with these unusual electrocardiographic changes of acute ischaemia, which require appropriate surveillance and treatment.
