Alterações Eletrocardiográficas com o Uso de Doxorrubicina Electrocardiographic Abnormalitys after Doxorubicin Use

The electrocardiogram (ECG) has proven useful in assessing patients using cardiotoxic chemotherapy. Although it is not an early marker, it is easy to perform, inexpensive and noninvasive. For best accuracy is important having a baseline ECG and if possible, one after each cycle of chemotherapy. If evolutionary changes in the electrocardiographic pattern are seen, more specific cardiac exams should be provided.
