Overview
- There are no particular ECG abnormalities for cardiac tumors. The ECG changes vary depending on the location of the tumor and do aid in the diagnosis of tumor in combination with other modalities.
Electrocardiogram changes
- There are no ECG abnormalities that are specific to cardiac tumors.
- Nevertheless, based on the area of involvement and propensity to metastasize, cardiac tumors exhibit ECG alterations that can aid in their detection.
| Tumor | ECG changes |
|---|---|
| Myxoma | Findings of left atrial enlargement, rarely arrhythmias, conduction abnormalities.[1] |
| Papillary Fibroelastoma | Nonspecific, patients may have atrial arrhythmias.[2] |
| Rhabdomyoma | Irregularities of the heart's rhythm, notably as heart block or ventricular tachycardia. The presence of arrhythmias is the most frequent manifestation of rhabdomyoma of the adult variety.[3] |
| Cardiac Fibroma | The ECG may reveal several abnormalities, such as left ventricular hypertrophy, right ventricular hypertrophy, bundle branch block, atrioventricular block, and ventricular tachycardia. |
| Cardiac Lipoma | Arrhythmias, including atrial fibrillation, ventricular tachycardia, and atrioventricular block, may result from interference with electrical conduction in the heart.[4] |
| AV nodal tumor | It should also be explored in situations involving sudden death and congenital heart block.[5] |
| Cardiac Sarcomas:
Angiosarcoma, Cardiac rhabdomyosarcomas, Fibrosarcoma and malignant fibrous histiocytoma, Leiomyosarcomas, Osteosarcomas of the heart |
Tumors that invade the myocardium may occasionally manifest with persistent Q waves or even ST alterations on the electrocardiogram (ECG) without coronary artery disease.[1]
