本文系用核听诊器和静息核素心血池显像技术,同时测定20例冠心病人和13例正常人左心功能的有关参数做对照性研究。结果显示:在核听诊器检查中,静息 LVEF 下降者7例。运动后 LVEF 有意义下降者共17例(85.0%)。在静息核素血心池显像技术中,整体 LVEF 下降者仅6例,而整体和/或局部 EF 下降者共15例(75%)。结论:静息核素心血池显像技术优于静息核听诊器技术。但后者如结合运动试验则略优于前者。
In this paper, the use of nuclear stethoscope and resting radionuclide blood pool imaging technique, simultaneous determination of 20 cases of coronary heart disease patients and 13 normal subjects left ventricular function parameters do comparative study. The results showed that: in the nuclear stethoscope examination, resting LVEF decreased in 7 cases. After exercise LVEF meaningful reduction in a total of 17 cases (85.0%). In resting radionuclide imaging, only 6 patients had a decrease in overall LVEF, whereas 15 (75%) experienced decreased global and / or local EF. Conclusion: Resting nuclide blood pool imaging technique is superior to resting core stethoscope technique. However, the latter is slightly better than the former in combination with exercise test.
