Deep and changeable negative T waves in a master athlete. The role of training

The article describes the case of a high level master cyslist (45 years old), asymptomatic and with a negative family history of cardiomyopathies, whose electrocardiogram presented significant alterations of ventricular repolarisation, specifically negative T waves from V1 to V6, with echocardiogram and magnetic resonance without alterations to justify them. The T waves normalised almost completely after a period of non‑training, returning to negative after the athlete began to train intensely again. Though not being able to exclude with certainty a form of cardiomiopathy in an initial phase, the picture was judged compatible with competitive sporting activity, also in relation to the absence of significant arrhythmias and the presence of an excellent cardiac performance.
