[Transient QT-interval prolongation and T wave inversion: diagnostic difficulties].

ST-T deviations are usually related to myocardial ischaemia, hypertrophy or myocarditis. Less common reasons are drugs action (such as digoxin, phenytoin) dyselectrolytaemia, brain ischaemia, anemia and pericardial effusion. However, in some cases, the reason of electrocardiographic changes is unclear. In presented case, we analise the potential influence of ibandronic acid on QT-interval prolongation and T-wave inversion, in patient treated for osteoporosis.
