摘　　要：目的 :探讨急性心肌梗塞 (AMI)并发右束支传导阻滞患者的临床特征 ,评价预后和临床意义。方法 :观察分析比较 1 989年 1月～ 1 999年 1 1月 1 86例 AMI患者心电图变化、血清肌酸激酶 (CK)、同工酶 (CK- MB)水平 ,及严重并发症及死亡率。所有数据经 χ2或 u检验。结果 :33例AMI并发 RBBB(占 1 7.7% )者预后明显差于未并发 RBBB者 ;其心肌酶水平 ,心力衰竭、心源性休克、心律失常等并发症和死亡发生率均增高 ;与糖尿病史、右室梗塞呈明显相关性 ,经统计学处理 ,两组有极显著性差异 (P<0 .0 1 )。结论 :AMI并发 RBBB多提示为大面积梗塞、心肌坏死严重 ,可作为一个预示危险的信号 ,高度重视 。objective:To investigate the clinical characteristics, and evaluate the clinical significance and prognosis of right Bundlebranch block(RBBB) in acute myocardial infarction (AMI)patients. Methods: One hundred eightysix cases of AMI patients were observed and classified comparation was made to analyses their levels of creatine kinase(CK)and its isoenzyme (CKMB) and their complications、mortalityall the data are checked by χ2 or utastResults:Among these 33 patients, complicated with RBBB (177%) had worse prognosis, higher serum level of creatine kinase (CK)and its isoenzyme MB(CKMB),more severe complicationsas heart failure, cardiogenic shock、Arrhythmia and much higher mortality rate than those without RBBBConclusion:RBBB is related to with the history of diabetes and the right ventricular infarction There was significant difference between two groups (P<001). Conclusion, in patient with AMI、RBBB might be a predictive sign of larger and severe infarction The prognosis is bad and more attention should be paid to it and that active therapy may improve their prognosis
