Primary cardiac tumors are exceedingly rare with variable clinical manifestations. This case involves a patient presentation of symptomatic complete heart block and cardiac imaging revealing a right atrial mass invading the myocardium consistent with Burkitt lymphoma on histopathology. The patient received definitive bradytherapy with a pacemaker and chemotherapy for the primary cardiac lymphoma. After three cycles of chemotherapy, the right atrial mass regressed significantly with restoration of atrioventricular conduction and no pacing burden. Primary cardiac lymphomas infrequently manifest as atrioventricular block and this case highlights cardiac masses as a potential etiology when evaluating new conduction disturbances and bradyarrhythmias.
原发性心脏肿瘤极为罕见，临床表现多样。该病例涉及一名患者，其出现有症状的完全性心脏传导阻滞，心脏成像显示右心房肿块侵犯心肌，组织病理学检查结果符合伯基特淋巴瘤。该患者接受了起搏器确定性缓慢性心律失常治疗及原发性心脏淋巴瘤化疗。三个化疗周期后，右心房肿块显著缩小，房室传导恢复，无需起搏负担。原发性心脏淋巴瘤很少表现为房室传导阻滞，该病例突出了在评估新出现的传导障碍和缓慢性心律失常时，心脏肿块作为潜在病因的可能性。
