Overview
There are no specific ECG findings associated with lung mass. However, lung cancer may metastasize to heart through lymphatic, hematogenous, or direct invasion. The most commonly involved part of the heart is pericardium followed by myocardium and finally endocardium. On an ECG, patient of lung mass with cardiac metastasis may present with nonspecific T wave and ST segment changes.
Electrocardiogram
There are no specific ECG findings associated with lung mass. However, lung mass (metastatic) may invade into mediastinum and heart (commonly through lymph nodes). Patients may have varied ECG findings depending upon the type of involvement.
- Lung cancer metastasized to heart may result in arrhythmia, myocardial infarction, cardiac tamponade, or congestive heart failure.[1]
- ECG generally depicts T wave and ST segment changes.[2]
