多普勒超声心动图(PDE)有许多测定左室舒张功能的参数指标,与心导管检查相比较,两者有很好的相关性。1988年Hitoshi等人首次提出收缩时间间期(LASTI)这一概念。它包括左房射血前期(LAPEP)和左房射血期(LAET)。本文就此问题进行了初步研究。
Doppler echocardiography (PDE) There are many parameters to measure left ventricular diastolic function parameters, compared with cardiac catheterization, the two have a good correlation. Hitoshi et al. First proposed the concept of contraction time interval (LASTI) in 1988. It includes LAPEP and LAET. This article conducted a preliminary study on this issue.
