急性下壁梗塞时的右心室受累,日益引起注意。本文用~(201)铊及~(99m)锝焦磷酸盐心肌双重显象法,评价急性下壁梗塞时右室受累的发生率及其临床情况。方法:78例急性下壁梗塞患者,男58例,女20例,年龄43～80(平均55)岁。在梗塞发生后20(平均10)小时内注射~(201)铊1.7～2.7微居里,5分钟后作心肌显象;在梗塞发作后至少24(平均32)小时注射~(99m)锝焦磷酸盐12微居里,1.5～2小时作显象。
Right ventricular involvement of acute inferior wall infarction, increasing attention. In this paper, ~ (201) thallium and ~ (99m) technetium pyrophosphate myocardial dual imaging method to assess the incidence of acute inferior wall infarction right ventricular involvement and its clinical situation. Methods: 78 patients with acute inferior wall infarction, 58 males and 20 females, aged from 43 to 80 (average 55 years). Infusions of ~ (201) thallium at 1.7 to 2.7 μC were injected within 20 (10 h) of the infarction and myocardial imaging was performed 5 minutes later; at least 24 (32 hours) after the onset of the infarct was injected with 99mTc Phosphate 12 micro-Curie, 1.5 ~ 2 hours for the development.
