本文利用多道生理记录仪对健康人及矽肺患者的肺阻抗微分时相改变进行了分析。对照组为正常男性72名;年龄27—50岁,平均39.03岁。矽肺组为单纯矽肺(男性)68例(Ⅰ期46例、Ⅱ期22例),年龄42—67岁,平均49.93岁.采用多道生理记录仪(上海医用电子仪器厂产)同步记录心电图Ⅱ导联、肺阻抗容积图、微分阶导数图、心音图。测定结果可以看出,右心室射血前期的间期,矽肺组比对照组延长17.9毫秒(t=5.6,
In this paper, the use of multi-channel physiological recorder of healthy people and patients with silicosis of lung impedance differential phase changes were analyzed. The control group of 72 normal men; aged 27-50 years, mean 39.03 years. Silicosis group was simple silicosis (male), 68 cases (stage Ⅰ 46 cases, stage Ⅱ 22 cases), aged 42-67 years, mean 49.93 years old. Using multi-channel physiological recorder (Shanghai Medical Electronic Instrument Factory) simultaneous recording of electrocardiogram Ⅱ Lead, pulmonary impedance volume diagram, differential order derivative chart, phonocardiogram. The results show that the duration of right ventricular ejection could be prolonged by 17.9 milliseconds (t = 5.6,
