title: [Electrocardiographic characteristics of a secondary tumorous lesion of the heart].
abstract: The main electrocardiographic signs of metastasis and spread of malignant tumors to the heart in 123 patients were studied. The most reliable electrocardiographic criterion of tumor metastasis to the heart are signs of a macrofocal lesion with no dynamics of changes characteristic of ischemic heart disease. Spread of a tumor to the heart and micronodal metastasis are characterized by the appearance of signs of microfocal myocardial lesion on the ECG. Specific carcinomatous pericarditis has all the ECG signs that are typical of pericarditis of any other etiology. Electrical alternation in an oncological patient is a convincing sign of metastatic lesion of the heart.
