近年来认为冠心病人舒张期功能的改变可能比收缩期功能检查更有意义,特别是局部精细的舒张期功能异常,可以作为早期缺血性心脏病灵敏的诊断指标,它可能先于收缩期功能的异常。本文主要报告一种定量地测定局部和整体左心室舒张期功能的方法。通过应用频率-范畴(frequencydomain)来分析付里叶系列的时间-放射性曲线,探测和鉴别心脏舒张期与收缩期功能的异常。为了评价其对缺血性心脏病诊断的灵敏度,测定
In recent years, the change of diastolic function in patients with coronary heart disease may be more meaningful than the systolic function test, especially the local fine diastolic dysfunction, as a sensitive diagnostic indicator of early ischemic heart disease, which may precede the systolic Abnormal function. This article reports mainly on a quantitative determination of regional and global left ventricular diastolic function of the method. Analyze the time-radiance curves of the Fourier series by applying a frequency domain to detect and identify abnormalities in diastolic and systolic function. In order to evaluate its sensitivity for the diagnosis of ischemic heart disease, determination
