近年来,日益认识到左心室收缩功能的测定可为各种心脏病的诊断、治疗和预后提供宝贵的资料。然而,至今仍以侵入性的心室造影为唯一的检查方法。自从Blumgart和Yens首先开始应用放射性示踪剂测定人体的血流速度以来,在显象装置、同位素和计算机技术方面取得了很大的改进,导致采用放射性核素血管造影检查心脏,特别是左心室,包括测定喷血分数、收缩失调和负荷放射性核素血管造影等,以诊断冠心病。这些方法可以重复,其测得的喷血分数和收缩失调与心室造影的结果相一致。本文概要综述放
In recent years, it has been increasingly recognized that the determination of left ventricular systolic function can provide valuable information for the diagnosis, treatment and prognosis of various heart diseases. However, invasive ventricular angiography is still the only test method. Since Blumgart and Yens first started to apply radiotracers to determine the blood flow velocity of the human body, great improvements have been made in imaging devices, isotopes and computer technologies that have led to the use of radionuclide angiography to examine the heart, especially the left ventricle , Including the determination of spurt score, systolic dysfunction and load radionuclide angiography to diagnose coronary heart disease. These methods can be repeated, and the measured ejection fraction and systolic dysfunction are consistent with the results of ventriculography. Summary of this article put
