title: Metastatic atrial tumor: case report with electrocardiographic-pathologic correlation.
abstract: This report describes a case in which the pre-mortem diagnosis of a right atrial metastasis from a bronchogenic carcinoma was made on the basis of distinctive PR segment (atrial repolarization) changes and atrial arrhythmias. The differential diagnosis of such PR segment deviations also includes functional changes, pericarditis, atrial infarction, and other types of atrial injury.
