摘要
对30例急性心肌梗塞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对比.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后.靶心图所测梗塞面积百分比与QRS记分法所测梗塞面积百分比相关良好(r=0.706,P<0.01),心肌灌注断层显像在前壁、前间壁、前侧壁和下壁心肌梗塞的定位上与心电图相比无明显差异,在后侧壁、后间壁、后壁和心尖部梗塞的定位上明显优于ECG(P<0.01).
Abstract This article reported the result of the quantification localization of 30 clinically confirmed acute myocardial infarction patients in comparison with that of ECG. A left ventricle model was used to correct the area calculated by the method of Bull's eye. The result indicated that the infarction area calculated by the corrected Bull's or method correlated closely with that determined by the ECG QRS scoring method (r=0.706, P<0.01). Myocardial infarctions of all 30 patients were detected by both ECG and myocardial perfusion tomographic imaging. The accuracy of localization of myocardial infarction by myocardial perfusion imaging was similar to that of ECG in the anterior wall, anterior septum, anterior lateral and inferior wall, but superior to that of ECG in the apex, postrior lateral, posterior septum, and posterior wall.
