Electrocardiographic changes suggesting ischemic heart disease in a case of lung cancer with myocardial metastasis / 대한내과학회지

ABSTRACT

Metastatic tumors to the myocardium proper are uncommon and difficult to diagnose because they have nonspecific signs and symptoms. Electrocardiogram (ECG) changes mimicking ischemic heart disease often develop when non-conducting tumor tissue replaces cardiac muscle. Hence, a high level of suspicion is required to differentiate ECG changes caused by myocardial metastasis from those caused by coronary heart disease in cancer patients. We describe a case of primary lung cancer with myocardial metastasis that showed diffuse ST segment elevation and T wave inversion on the ECG, with a relevant literature review.
