Electroencephalography (EEG) recordings obtained after craniotomy are difficult to interpret because of the presence of a breach rhythm (BR) consisting of unfiltered high-voltage physiological waveforms, sometimes with a spiky and irregular morphology, that can mimic interictal epileptiform abnormalities and may therefore lead to misinterpretations. In this article, we review EEG features of BR and give some technical tips to properly interpret BR and to make a correct differential diagnosis with epileptiform abnormalities. As BR itself has no relationship to epilepsy, it is very important to adopt a "conservative" reading, having a high threshold to call epileptiform abnormalities.
开颅术后获得的脑电图（EEG）记录由于存在由未滤波的高压生理波形组成的破裂节律（BR）而难以解释，有时形态呈棘状和不规则，可能模仿发作间期癫痫样异常，因此可能导致误诊。在本文中，我们回顾了 BR 的 EEG 特征，并提供了一些技术提示，以正确解释 BR 并与癫痫样异常进行正确的鉴别诊断。由于 BR 本身与癫痫无关，因此采用“保守”的阅读方式非常重要，即对癫痫样异常的判断阈值要高。
