摘　　要：以 10例正常人为对照 ,对 31例心肌梗塞 (下称心梗 )患者进行了放射性核素心肌断层显像、心室显像及相位分析。根据心肌断层结果 ,按梗塞部位分为 组 (前壁、心尖、侧壁 )、 组 (间壁、伴或不伴前壁、心尖 )、 组 (下壁、后壁 )。结果表明 ,与对照组比较 , 组、 组、 组 L V相角程有显著差异 , 、 组 RV相角程有差异显著。相位图、振幅图及动态相位显示的病变区与心肌断层基本相符 ,相位图显示的病变区域更为广泛。提示相位分析不仅能提供心梗、缺血部位 ,还能反映心肌顺应性、协调性改变 。In contrast to 10 cases of normal persons,the radionuclide myocardial SPECT imaging,ventriculography and the phase analysis were studied in 31 cases with myocardial infarction(MI)Based on the results of SPECT and according to the infarction location the MI patients were classified as Group Ⅰ(anterior wall,apex,and lateral wall),GroupⅡ(interventricular septum,with or without anterior wall and apex)and GroupⅢ(inferior wall and posterior wall)Results showed that in comparison with normal group,there exist remarkable differences on LV phase angle width among GroupⅠ、Ⅱ、Ⅲ and remarkable differences on RV phase angle width between Group ⅡandⅢThe sick area shown by phase,amplitude and phase cine basically conform to myocardial SPECTThe sick area shown by phase was still widerThis indicates the phase analysis can not only suggest the locations of myocardial infarction and ischemia,but also reveal the changes of myocardial compliance and coordination,providing a certain basis for the diagnosis on right ventrical infarction
