Evidence for sinoatrial blockade associated with high dose cytarabine therapy.
Cytarabine therapy is rarely complicated by cardiotoxicity. The present report describes the clinical course of a 35-year-old female patient with acute myelogenous leukemia in complete remission, who developed sinus bradycardia while on high dose cytarabine as a consolidation therapy. The electrocardiographic findings suggested that bradycardia was most probably the result of sinoatrial blockade. The available information regarding a possible association of cytarabine with disturbances of cardiac rhythm is reviewed.
