Following the direct M response, peripheral nerve stimulation frequently evokes a second wave which shows all characteristics of an ephaptic response. The antidromic impulse or back response, which is always associated, is detected by a double stimulation technique. The ephaptic response seems not to be related to any specific nerve or muscle pathology, as it is also observed in normal subjects. It is therefore important to differentiate the ephaptic response from a late potential or a double discharge, the latter two having pathological significance.
在直接M反应之后，外周神经刺激常常会诱发第二个波，该波表现出电紧张反应的所有特征。总是与之相关的逆向冲动或反向反应通过双重刺激技术来检测。电紧张反应似乎与任何特定的神经或肌肉病变无关，因为在正常受试者中也能观察到。因此，将电紧张反应与具有病理意义的晚电位或双重放电区分开来很重要。
