Abstract
Based on our previous experience in doxorubicin-treated patients, in whom we observed a significant increase of ventricular recovery time indexes, we analyzed these non- invasive parameters of myocardium electrical instability in forty-three 5-fluorouracil-treated patients, to test the hypothesis of a mechanoelectrical disarrangement occurring in 5-fluorouracil (5FU) cardiotoxicity. All patients enrolled were studied at the first presentation and following chemotherapy. The study showed the absence of any significant changes in recovery time indexes or in other electrocardiographic parameters. Our data suggest that 5FU does not interfere with electrical properties of myocardial fibers.
