老年与青壮年心功能应用颈动脉搏动图和阻抗心动图检查的初步观察

Preliminary Observation of the Application of Carotid Arteriogram and Rheocardiogram in Heart Function Analysis of the Elderly and Youth

本工作对27例健康老人及56例健康青壮年进行了颈动脉搏动图和阻抗心动图检查,通过两组间无创性心功能测定数据的相互比较,说明老年人心脏生理功能变化的一些特点。结果表明:与青壮年组比较,(1)老年组 Q-S_2I 和 PEPI 均显著延长(P<0.05);LVETI 和 PEP/LVET 则无明显变化(P>0.05)。(2)老年组 Heather 指数、△V、CO、CI 均显著减少(P<0.01)。这表明老年人心脏功能较青壮年明显减退,而 STI 及阻抗心动图能够比较客观地反映这种变化。

In order to demonstrate some physiological changes of the old person's heart,harmless experimental techniques as carotid arteriogram and Rheocardiogram werecarried out on 27 healthy persons aged 61-77 years and on 56 of 21-39 years. Theresults showed that (1) the old persons had both longer Q-S_2I and longer PEPI thanthe younth (P<0.05). No significant changes were found on LVETI and PEP/LVET (P>0.05). (2)old persons also had the reduced Heather's Index, ΔV, CO andCI (P<0.01). The results suggested that the heart function of old people was remar-kablly degenerated, which could be reflected by STI and Rheocardiogram.
