Metastatic involvement of the left atrium revealed by electrocardiographic Ta segment change.
We describe a case in whom an unusual alteration of the atrial repolarization observed on routine electrocardiogram (Ta segment depression) led to the echocardiographic diagnosis of metastatic involvement of the left atrium by a lung cancer. Electrocardiographic abnormalities in the metastatic involvement of the heart are non specific but observation of new changes may suggest the diagnosis and modify the staging and the treatment.
