Electrocardiographic manifestations of heart metastasis from a primary lung cancer.
Though acute myocardial infarction is one of the most frequent causes of ST segment elevation, there are other, less frequent, reasons for such electrocardiographic changes. In the present case, a cardiac metastasis from a squamous cell lung carcinoma was responsible for these changes. The secondary lesion was located in the apex of the left ventricle and induced an ECG alteration mimicking myocardial ischaemia. The literature includes few reports that describe the relation between electrocardiographic changes and heart metastases, since heart metastases are not usually discovered except at autopsy.
