Electromyography (EMG) of diaphragm (Edi) and intercostal muscle (Ein) in 30 healthy volunteers and 28 patients with cor pulmonale or pulmonary fibrosis were analysed. The results show that (1) there is no obvious activity of Ein to be observed and the frequency spectra are stable when the healthy volunteers breath quietly, (2) the activity of Ein and the amplitude of Edi increase when patients are in compensation stage, (3) the patients with serious respiratory failure, the amplitude of Edi decreases remarkably, (4) the frequency spectras of Edi appear wave-like changes with the breathing pattern of patients.
分析了30名健康志愿者以及28名患有肺心病或肺纤维化患者的膈肌肌电图（Edi）和肋间肌肌电图（Ein）。结果显示：（1）健康志愿者安静呼吸时，未观察到Ein有明显活动，且频谱稳定；（2）患者处于代偿期时，Ein活动及Edi波幅增加；（3）严重呼吸衰竭患者，Edi波幅显著降低；（4）Edi频谱随患者呼吸模式呈现波浪状变化。
