本组用成都亚光厂生产的SCZW—1型血液微分阻抗仪配以上海医电厂生产的XDY-1型双联心电、心音图机,检测县医院健康工作人员113人(男50,女63),年龄10～19岁12例、20～29岁22例、30～39岁24例、40～49岁29例、50～59岁16例、60以上10例。检测项目包括基础阻抗(ΔZ)、E_2-E_3极间距(L)、一阶导数最大值(dz/dt_(max))SV、CO、CI、EF、每搏作功(SW)、Q-B间期(Q-B)、Q-Z间期(Q-Z)、B-X间期(B-X)、Heather指数(HI)、血管顺应性(C)、总外周阻力(TPR)和PEP/LVET。结果提示:①基础阻抗Z_0值与胸腔容积呈负相关,两组电极带,尤其是
The group produced by the Ya-Guang plant in Chengdu SCZW-1 blood differential impedance meter coupled with the Shanghai Medical Power Plant produced XDY-1-type dual ECG, heart sound machine, the detection of county hospital 113 health workers (male 50, female 63), 12 patients aged 10 to 19 years, 22 patients aged 20 to 29 years, 24 patients aged 30 to 39 years, 29 patients aged 40 to 49 years, 16 patients aged 50 to 59, 10 60 cases. The test items include basic impedance (ΔZ), E_2-E_3 pole spacing (L), first derivative maximum (dz / dt max) SV, CO, CI, EF, SW, QB interval QB interval, QZ interval, BX interval, Heather index, C, TPR and PEP / LVET. The results suggest that: ① basic impedance Z_0 value and the chest volume was negatively correlated, two sets of electrode strips, especially
