摘要
120例健康老人分别测试了心脑肺功能,其中20例同步作了三种检测。结果显不与老年前期组相比,老年组的心功能略有减退,但无显著性差异,脑功能出现α波频率减慢,波幅降低,指数减少,调节调幅不良的增多,α_1频带能量及α_2频带的平均功率均降低,肺功能呈现FVC、FV_1.0％、FEF_(25-75)、MVV显著降低,RV/TLc％增高,Raw、Gaw、SGaw、SRaw、VTG无改变。20例同步者分吸烟与不吸烟两组,结果吸烟者的LV增大,EF降低,α_1、α_1频带功率显著降低,SGaw降低,SRaw增高,VTG增大。
Cardiac, cerebral and pulmonary functions were studied in 120 old people, 20 cases of them were studied silmutaneously with three methods.The reaults showed that in comparison with preaged men, there was no significant changes of the cardiac function in old persons. In compute electroencephalography topography(CET) the fenquency of α wave became slow, the amplitude lowered, and the α index decreaaed. With respect to the pulmonary function, the forced vital capacity (FVC), first second forced volume/forced expiratory volume (FEV)1.0%, forced expiratory flow (FEF)25-75%, maximal voluntary ventilation(MVV) decreased, and the residual volume /total lung capacity(RV/TLC) % increased significantly. In the smoking group, there were left ventricular (LV) enlargement, and ejection fraction (EF) decreased. And CET showed decreases of α_1, α_2, β spectral power. The pulmonary function showed no significant differences in FVC, FEV1.0%, FEF25-75%, MVV and RV/TLC/TLC% between the smorkiny and non—smorking groups though specific airway condutance (SGaw), decreased, and specific airway resistance (SRaw) and of intrathoracic gas volume (VTG) increased in the smoking group.
