近来,临床研究指出急性下壁心肌梗塞患者并有右心室功能障碍者比以往怀疑的要多。本文旨在评价非侵入性放射性核素闪烁图及超声心动图诊断右心室梗塞和功能障碍的价值。方法:26例急性穿壁性心肌梗塞患者于入院后72小时内进行放射性核素闪烁图、超声心动图和血液动力学检查。入院后24至48小时,在静脉注射15毫居里~(99m)锝—焦磷酸盐(~(99m)T_c—pyp)后作心肌梗塞放射性核素闪烁图。24小时后再用~(99m)锝标记
Recently, clinical studies have pointed out that more patients with acute inferior myocardial infarction and right ventricular dysfunction than ever suspected. This article aims to evaluate the value of noninvasive radionuclide scintigraphy and echocardiography in the diagnosis of right ventricular infarction and dysfunction. METHODS: Twenty-six patients with acute transmural myocardial infarction were examined by radionuclide scintigraphy, echocardiography, and hemodynamics within 72 hours of admission. 24-48 hours after admission, a scintigraphy of myocardial infarction was performed after intravenous injection of 15 millicuries of 99m Tc-pyrophosphate (~ (99m) T_c-pyp). Twenty-four hours later with ~ (99m) technetium labeling
