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.

ECG Changes in Cardiac Tumors

Tumor	ECG changes
Myxoma	findings of left atrial enlargement, rarely arrhythmias, conduction abnormalities
Papillary Fibroelastoma	Nonspecific, patients may have atrial arrhythmias
Rhabdomyoma	Irregularities of the heart's rhythm, notably as heart block or ventricular tachycardia
Fibroma	The ECG may reveal several abnormalities, such as left ventricular hypertrophy, right ventricular hypertrophy, bundle branch block, atrioventricular block, and ventricular tachycardia.
Lipoma	Arrhythmias, including atrial fibrillation, ventricular tachycardia, and atrioventricular block, may result from interference with electrical conduction in the heart.
AV nodal tumor	It should also be explored in situations involving sudden death and congenital heart block.
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.
