摘　　要：目的探讨冠心病合并束支传导阻滞SPECT显像特点及与心肌缺血的相关性。方法回顾冠心病合并束支传导阻滞患者(研究组52例)与无束支传导阻滞的冠心病患者(对照组201例)SPECT显像特点及与心肌缺血相关性。结果研究组SPECT心肌灌注断层显像表现为缺血性改变阳性率高(86.31%),同时存在(3～4处)的缺血部位多,两组比较差异有显著性(P<0.001,<0.05);静态门控心血池显像位相分析,研究组多异常,对照组基本正常。结论冠心病合并束支传导阻滞与心肌缺血程度及病变范围相关,预示冠心病合并束支传导阻滞时冠状动脉病变广泛而严重。Objective: To explore the correlation of SPECT MIBI feature and myocardial ischemia in coronary heart disease(CHD)with bundle branch block(BBB).Methods:~99m Tc-MIBI ECT studies were performed in 253 patients with CHD.Patients were divided into group A(52 cases with BBB)and group B(201 cases without BBB).Results:(1)The positive rate of ECT MIBI myocardial ischemia was 85.36% in group A,it was higher than in that in group B;3～4 ischemic parts in group A was more than in groupB.(2)Edquilibrium radionuclide ventriculography(ERV)was abnormality by phase analysis in patients with BBB.There was a significant difference between two group.Conclusion:CHD with BBB is significantly correlated to the degree and scope of the myocardial ischemia,CHD with BBB is more serious than CHD without BBB.
