Complex ventricular arrhythmia induced by overuse of potassium supplementation in a young male football player. Case report.
People practising regular physical activity usually drink hydrosaline beverages. In this study is reported the case of a young football player suffering from premature ventricular beats. He used to take regularly an hydrosaline supplementation which gave him a daily intake of potassium of about 5 g. A stress test on a cycle ergometer showed many monomorphus premature ventricular beats which disappeared when the heart rate was higher than 110 beats/min. Moreover, 3629 polimorphus premature ventricular beats were recorded during a 24 hr ECG monitoring. At the time of the first examination, the plasma potassium concentration was 7,8 mEq x l(-1). The football player was then suspended from practicing sport and he was asked to stop his intake of potassium. The clinical examination was repeated after 3 and 6 months and no ventricular arrhythmias were observed during the stress test as well as during the 24 hours ECG monitoring. The plasma potassium concentration was normal again. The present case report is an example of how the misuse of saline supplementations could result in hyperkalemia and how this condition may lead to ventricular arrhythmias.
