左心收缩时间间期(Left Ventricular Systolic Time Intervals, LVSTIs)的测定是反映左心室功能的主要方法之一。经研究表明,此法与心导管查得的某些血流动力学指标相关良好,并具有检测简便、重复性好等优点,业已应用于临床。但有关围产期新生儿的报道不多,国内尚未见有记叙。为此,本文就54例围产儿共98例次的LVSTIs检测,从中分析并探讨生后6天内LVSTIs的变化规律。对象与方法一、对象:54例均为温州医学院附属第一医院产科出生的足月儿,其中男性28例、女26例。年龄为初生～130小时不等,出生
Left ventricular systolic time interval (Left Ventricular Systolic Time Intervals, LVSTIs) determination is one of the main methods to reflect left ventricular function. The study shows that this method and cardiac catheterization of certain hemodynamic indicators related well, and has the advantages of simple detection, good reproducibility, has been used in clinical. However, there are few reports on perinatal newborns, and there are no reports in China yet. To this end, this article on 54 cases of perinatal children a total of 98 cases of LVSTIs detection, from analysis and explore changes in LVSTIs 6 days after birth. Subjects and methods First, the object: 54 cases were born in the First Affiliated Hospital of Wenzhou Medical College full-term children, including 28 males and 26 females. Age of newborn ~ 130 hours, born
