WebThe breach rhythm, also known as the breach effect, is a benign EEG pattern with an epileptiform morphology, caused by a skull abnormality. A focal skull defect, like after a craniotomy, can cause an increase in the amplitude of alpha, beta, and mu rhythms, leading to the breach effect.
WebJul 26, 2016 · The most common cause of focally enhanced beta activity is the breach rhythm. This is usually the consequence of intracranial surgeries requiring a craniotomy or burr hole ( Figs. 8.1 and 8.2 ). Less often, the breach rhythm results from a skull fracture. Skull defects enhance the voltage of frontal fast rhythms as much as threefold.
