Delayed cerebral T-waves after head trauma

One day after a blunt, severe head trauma, an initially normal ECG of a 45 year old man showed marked, nearly symmetric T-wave inversions and prolongation of QT/QTc. Before, during, or afterwards, the patient did not offer any complaints referable to his cardiovascular system. Two months later, his ECG was almost normal; seven months later, a cardiolite stress test was normal. A small increase in serum creatine kinase and in its MB fraction was probably due to a chest trauma but possibly suggests cardiac myocytolysis related to stress induced catecholamine release.
