最近亦有将运动或潘生丁负荷铊心肌显象时出现再灌注者(re-perfusion)作为SMI的意见。本文就此类病人中运动负荷试验的意义及试验结果的解释,结合实际病例予以论述。例1男性,61岁,自1963年以来偶感劳累时呼吸困难,1981年就诊时发现心杂音,超声波示二尖瓣狭窄。于1990年1月为详查而入院,体检脉率61次/分,不齐,S_1亢进,有开瓣音及心尖部舒张期隆隆样杂音,超声波示典型风湿性改变,瓣口面积约1cm~2,无返流,左
Recently, re-perfusion has also been reported as an SMI in exercise or dipyridamole-loaded thallium myocardial imaging. In this paper, the significance of exercise load test in such patients and the interpretation of test results, combined with the actual case to be discussed. Example 1 Male, 61 years old, having occasional senile dyspnea since 1963, heart murmur was observed at the time of visit in 1981 and stenosis of the mitral valve was revealed by ultrasound. In January 1990 for the detailed investigation and admission, physical examination rate of 61 beats / min, missing, S_1 hyperthyroidism, atrial valve and apex diastolic rumbling like noise, typical rheumatic ultrasound showed change, the valve orifice area of about 1cm ~ 2, no reflux, left
