[Pseudonormalization of repolarization during physical exercise and the hemodynamic findings]

The meaning of normalization of abnormal T waves during exercise is still unclear, twenty patients with this electrocardiographic pattern during treadmill stress test were studied with coronary arteriography. They were classified in two groups: Group I: In which 3 patients had isolated "pseudonormalization" of the T wave, and Group II with "pseudonormalization" of the T wave plus a positive stress test or an old myocardial infarction. Results allowed us to conclude that this phenomenon per se is not a diagnostic clue of coronary injury; however when we observe it associated with a positive stress test or an old myocardial infarction it may be indicative of severe and multiple coronary vessel injury.
