从~(99m)锝-焦磷酸盐弹丸式静脉注射最初通过心脏期间的高频时间-放射性曲线可以检查右心室喷血比数。作者检查了43例急性心肌梗塞患者,确立了22例无心肺疾病证据患者的正常值,对右心室和左心室的喷血比数进行了讨论。无心肺疾病患者的右心室平均喷血比数为0.52±0.04,左心室平均喷血比数为0.60±0.06,左心室与右心室喷血比数的平均比值是1.17±0.10。在随后得到的~(99m)锝-焦磷酸盐显影图中,无1例对照患者显示异常放射性浓集区。急性前壁或前外侧壁心肌梗塞患者显示左心室喷血比数降低,但未见右心室喷血比数降低。急
Right ventricular ejection fraction can be checked from ~ (99m) technetium-pyrophosphate bolus intravenous high-frequency time-activity curves initially passed through the heart. The authors examined 43 patients with acute myocardial infarction and established normal values for 22 patients with evidence of no cardiopulmonary disease. The ratio of spiking to the right and left ventricle was discussed. The mean right ventricular ejection fraction was 0.52 ± 0.04 in patients with no heart and lung disease, the average left ventricular ejection fraction was 0.60 ± 0.06, and the average ratio of left ventricular to right ventricular ejection fraction was 1.17 ± 0.10. In the resulting ~ (99m) technetium-pyrophosphate development, none of the control patients showed abnormal radioactive concentrations. Patients with acute anterior or anterolateral wall myocardial infarction showed a decrease in the number of left ventricular ejection fractions, but no reduction in the number of right ventricular ejection fractions. anxious
