58±15(25～80)岁的79例受检者分为三组:第一组查无心脏疾病证据者为正常组,共14例;第二组首次 Q 波型急性心肌梗塞患者44例,其中23例为前壁梗塞,21例为下壁梗塞;第三组为21例扩张型心肌病伴充血性心衰、左室射血多数(LVEF)<40%而没有近期心肌梗塞的临床或心电图证据。检查方法先取右前斜位30°,~(99m)Tc-HSA(人血清白蛋白)15～20mci 于近端大静脉注入后,以心电图 R 波门控 r 照相机用首次通过法采集舒张末期(ED)和收缩末期(ES)的图帧。然后再取左前斜位进行平衡法采集,获取心动周期内16帧图帧。在右室图像上画5根线。前4根线画在右前斜位图
58 ± 15 (25 ~ 80) years of 79 subjects were divided into three groups: the first group was no evidence of heart disease were normal group, a total of 14 cases; the second group of Q-wave acute myocardial infarction in 44 patients , Of which 23 cases of anterior wall infarction and 21 cases of inferior wall infarction; the third group of 21 cases of dilated cardiomyopathy with congestive heart failure, left ventricular ejection fraction (LVEF) <40% without recent myocardial infarction Or ECG evidence. The test method to take the right anterior oblique 30 °, ~ (99m) Tc-HSA (human serum albumin) 15 ~ 20mci in the proximal intravenous injection of ECG R wave gated r camera with the first passage of end-diastolic acquisition (ED ) And end-systolic (ES) frames. And then take the left anterior oblique balance acquisition method, access to cardiac frame 16 frames. Draw 5 lines on the right ventricle image. Draw the first 4 lines in the right front oblique image
