ECG mimicking acute myocardial infarction during heart involvement by lung neoplasm

Electrocardiographic abnormalities are common with tumor invasion of the heart. Pronounced lateral ST segment elevation in the absence of myocardial infarction occurred in a patient with epidermoid carcinoma of the left lung. Tomography showed the presence of tumor invasion of the heart. Prolonged ST segment elevation without Q waves seems to be a sign for tumor invasion of the heart.
