RESUMO
The article discusses the experience in surgical treatment of tumors of the heart in 34 patients in clinics of cardiosurgery at the Riga Medical Institute and the Institute of Cardiology and Cardiovascular Surgery of Havana (Cuba). Twenty-five patients underwent operations for benign tumors of the heart (16 myxomas, 2 leiomyomas, 2 fibromas, 1 lipoma, 1 angiofibroma, 2 coelomic cysts) under extracorporeal circulation, with 4% lethality. No recurrences were encountered in follow-up periods of 5 months to 14 years. Nine patients had malignant tumors; the tumor was removed successfully in 3 of them, even with resection and prosthetic replacement of the outflow tract of the right ventricle. Only 3 of the patients (33%) who were operated on had a follow-up period of more than 1 year.

The incidence and diagnostic criteria of heart rhythm disorders associated with a permanent pacemaker were assessed on the basis of data, obtained at a single electrocardiography in 1165 patients and continuous ECG recording in 49 patients. A high (94.4%) incidence of the spontaneous and induced rhythm competition at asynchronous stimulation has been demonstrated, indicating that the use of this stimulation regimen should be abandoned. The inhibition of a unipolar pacemaker by myopotentials at regular physical activity is rather uncommon and has no clinical value. VVI stimulation is often (45.2%) associated with variants of escape-capture bigeminy.
