随着兆伏放射治疗应用的增加,放射性心脏病的发病率明显增高。放射性心脏病的临床表现包括心包积液、急性心包炎、缩窄性心包炎、“心肌病”、冠心病及瓣膜病,可以在放疗后若干年内不明显,传导系统损害甚少。本文报告一例放射治疗后发生高度房室阻滞的病例。患者男性,26岁,1966年因何杰金氏病接受了4000拉德的钴治疗,采用斗蓬式照射,心尖区用保护物遮盖,未用化疗。82年1月,患者开始晕厥发作。心电图证实为右束支阻滞及Ⅰ~(?)房室传导
With the application of megavoltage radiation therapy, the incidence of radiation heart disease is significantly increased. The clinical manifestations of radiation heart disease include pericardial effusion, acute pericarditis, constrictive pericarditis, “cardiomyopathy”, coronary heart disease and valvular disease, which can be obscured within a few years after radiotherapy, with minimal damage to the conduction system. This article reports a case of a high incidence of atrioventricular block after radiotherapy. Male, 26 years old, 1966 Gothenburg’s disease due to received Radon treatment of 5 000 rad, the use of cloak-type irradiation, apical area covered with protective material, without chemotherapy. In January 82, the patient started to have a syncope. ECG confirmed right bundle branch block and Ⅰ ~ (?) Atrioventricular conduction
