Rare complication of doxorubicin-induced complete heart block in a patient with Hodgkin's lymphoma: a case report.

Anthracyclines are associated with cardiotoxic manifestations that are mainly dose-dependent, with onset varying from a few days to many years after stopping treatment. Frequent monitoring for toxic manifestations, early detection, cessation of anthracycline use and appropriate treatment is the key to preventing morbidity and mortality. Complete heart block with doxorubicin use in Hodgkin's lymphoma is rarely reported, and is a severe toxic manifestation necessitating withdrawal or changing of regimen to etoposide + bleomycin + vinblastine + dacarbazine (EBVD), as in this case.
