本文用无创性心功能检测方法测定108例健康儿童和126例健康成年人的心脏功能,并对各项心功能指标逐一进行统计分析。结果提示:SV、CO、PEP、LVET等九项指标随年龄的增长而增大,且三组间有高度显著性差异(P<0.01);CI、HI、C—dZ/dt、O—dZ/dt、Q—Z间期等五项指标在两儿童组间无显著性差异(P>0.05),但在儿童与成人组间有高度显著性差异(P<0.01);EF、PEPI、LVETI、PEP/LVET、O/C等五项指标在三组间均无显著性差异(P>0.05)。由此可以看出:学龄前儿童的心功能指标有些与成年人差异很大,所以需要一套特殊指标作为参考,而不宜采用已有的成人标准值来判定儿童的心脏功能。
In this paper, heart function of 108 healthy children and 126 healthy adults were determined by noninvasive cardiac function test, and each cardiac function index was statistically analyzed one by one. The results indicated that the nine indexes such as SV, CO, PEP and LVET increased with age, and there was a highly significant difference among the three groups (P <0.01); CI, HI, C-dZ / dt, O-dZ There was no significant difference between the two groups (P> 0.05), but there was a significant difference between children and adults (P <0.01). EF, PEPI, LVETI , PEP / LVET, O / C and other five indicators no significant difference between the three groups (P> 0.05). It can be seen: preschool children’s heart function index and adults vary widely, so you need a set of special indicators as a reference, rather than using the existing adult standard value to determine children’s heart function.
