本文对３０例ＡＭＩ患者进行心肌灌注断层显像的定位和定量分析，并与ＥＣＧ的定位和定量分析进行比较，对靶心图存在的缩小和扩大病灶因素用左室模型进行校正。结果表明：心肌灌注断层显像在后侧壁、后间壁、后壁和心尖部梗塞的定位上明显优于ＥＣＧ，经模型校正后靶心图所测梗塞面积百分比与ＱＲＳ记分所测梗塞面积百分比相关良好（ｒ＝０．７０６，Ｐ＜０．１）。预后不良组无论靶心图或ＱＲＳ记分所测梗塞面积均明显高于预后较好组。 In this paper, 30 patients with myocardial infarction AMI localization and quantitative analysis of myocardial perfusion imaging and ECG positioning and quantitative analysis were compared to reduce the size of the target map and to expand the lesion factors were corrected by left ventricular model. The results showed that myocardial perfusion tomography was superior to ECG in posterior wall, posterior parietal wall, posterior wall and apical infarction. The percentage of infarcted area measured by model-corrected bull’s-eye images was correlated with percentage of infarcted area measured by QRS score Good (r = 0.706, P <0.1). Prognosis of patients with poor prognosis group regardless of bull’s-eye or QRS scores were significantly higher than the prognosis of the better group.
