摘要
以不同频率刺激及剪断家兔颈部两侧迷走神经,记录处理后5min内呼吸运动曲线和心电图。结果显示,不同频率刺激后家兔的呼吸幅度降低、呼吸频率升高、心率降低。剪断迷走神经后呼吸频率降低,呼吸幅度和心率均升高。所以,刺激家兔迷走神经后,能不同程度地调节呼吸和心率。
The vagus nerves were stimulated with different frequency and cut off respectively. The frequency and intensity of breath and heart rate were. recorded and calculated. Compared with the control, the breath intensity and heart rate of the treatment reduced, the breathing frequency increased after stimulation. After cutting, the breathe intensity increased to the biggest, the breathing frequency reduced, the heart rate increased. Stimulation to the vagus nerve with different frequency could adjust the breath and heart rate in certain degree.
