Özet
Cardiac repolarization is detected on the surface 12-lead ECG as the T wave. In general the direction of the T wave is in the same direction with the QRS complex. In case of myocardial injury, recovery may be delayed regionally causing subendocardial muscle fibers recover first. Repolarization from endocardium to epicardium results inversion of the T waves. Although inverted T waves are constantly seen in electrocardiograms and that can be associated with myriad of pathologies or nonspecific changes, it is often a manifestation of myocardial ischemia. Giant deep inverted T waves are a rare evidence for the clinical conditions. Giant T waves can be seen with apical (Yamaguchi) variant of hypertrophic cardiomyopathy, high intracranial pressure, subarachnoid hemorrhage, severe myocardial ischemia, pulmonary embolism and in posttachycardia syndrome. We report here two cases with giant inverted T waves after myocardial infarction and discuss the potential mechanisms in the light of the literature. Copyright © 2012 by Türkiye Klinikleri.
