Mechanical heart compression, including that from mediastinal tumor, may cause Brugada-like ECG pattern. Such ECG pattern might also be observed in intracardiac tumor obstructing the right ventricular out"ow tract (RVOT). Eight cases with Brugada-like ECG and tumors involving RVOT have been described so far; 4 growing in the mediastinum (with one example of in"ammatory mass), 3 with intracardiac location, and 1 being an organized pericardial hematoma. The authors present other 3 cases of intracardiac metastatic tumors in RVOT and Brugada-like ECG pattern with coved ST-segment elevation in the right precordial leads. All patients had negative history of cardiovascular disease or familiar malignant arrhythmia occurrence. ECG were done routinely; none of the patients had chest pain or an increased level of cardiac troponins. In all patients, neoplastic disease was at advanced stage. A 76-year-old male, had a history of four neoplasms: bladder cancer was being treated with chemotherapy, while prostate, tongue, and lung cancers had been resected years ago and no signs of local relapse were found. A 78-year-old female, was diagnosed with colon cancer 1 month after an episode of venous thromboembolism. Six months after the resection of cancer, second focus of adenocarcinoma was found in the rectum. Third patient, a 65-year-old-male had undergone nephrectomy for renal cancer a year before cardiac metastasis diagnosis.
