本文旨在将活体中闪烁扫描时梗塞的部位、大小与尸检时的发现作比较。作者曾连续对550例急性心肌梗塞患者用铊—201作扫描,33例死亡,其中23例经尸检,构成本文研究的基础。此23例于铊—201检查时均未服用β—阻滞剂,采用目测法以及用扫描器结合计算机计算的方法来测定闪烁图中灌注不良区占整个左心室的百分比,前者以ESC％、后者以CSC％来表达。尸检时,将心脏横切为1厘米厚的切片,确定梗塞的部位与范围。梗塞区占整个左心室的百分比以PM％来表示。测定ESC％,CSC％及PM％的皮尔逊线性相关系数及回归线。所有患者于生前均有铊—201活性缺损或减少区,这些区域被认为就是梗塞之处。1例心电图表现为左束枝传导阻滞者,铊—201测定时清楚地看到了梗塞区。2例心电图无
The purpose of this article is to compare the size of the infarct and the findings at autopsy in vivo with scintigraphy. The authors have consecutive series of 550 patients with acute myocardial infarction using thallium -201 scan, 33 patients died, of which 23 were autopsy, constitute the basis of this study. The 23 cases of thallium -201 test did not take β-blockers, the use of visual methods and computerized method with a scanner to determine the perfusion map of poor perfusion area accounted for the percentage of the entire left ventricle, the former with ESC% The latter is expressed in CSC%. Autopsy, the heart cross-sectioned to 1 cm thick, to determine the location and extent of infarction. The percentage of infarcted area in the entire left ventricle is expressed as PM%. Pearson’s linear correlation coefficient and regression line of ESC%, CSC% and PM% were determined. All patients had defects or areas of thallium-201 activity during their lifetime, and these areas were considered to be infarctions. 1 case of ECG showed left bundle branch block, thallium -201 determination clearly see the infarct area. 2 cases without ECG
