为了解刺激伪迹和肌电对豚鼠面神经逆行诱发电位（Ａｎｔｉｄｒｏｍｉｃｅｖｏｋｅｄｐｏｔｅｎｔｉａｌ，ＡＥＰ）的影响，观察了不同刺激条件下刺激伪迹的改变及其和ＡＥＰ的时序关系；使用肌松剂前后肌电及ＡＥＰ波形成分的变化，结果表明：过大的刺激伪迹影响ＡＥＰ早期成分的识别。选择适当的刺激部位、适宜的刺激信号波宽、极性及强度可使刺激伪迹和ＡＥＰ充分分离；在生理状态下，肌电不影响ＡＥＰ的识别，但在病理状态下，仍应注意肌电对ＡＥＰ晚期成分的影响。
In order to understand the effects of stimulus artifact and electromyography on the facial nerve retrograde evoked potential (AEP) in guinea pigs, the changes of stimulus artifact and the relationship between them and AEP were observed under different stimulus conditions. The electromyography and AEP The changes of the waveform components show that the excessive stimulus artifacts affect the identification of early AEP components. Select the appropriate stimulation site, appropriate stimulation signal wave width, polarity and intensity can make the stimulation artifacts and AEP fully separated; under physiological conditions, EMG does not affect the AEP recognition, but in the pathological state, should pay attention to muscle Effect of electricity on the late components of AEP.
