If seizure discharge causes square waveforms, what adjustment should be made to the sensitivity?

When a seizure discharge results in square waveforms on an EEG, it indicates a pattern that is significantly more pronounced or has a greater amplitude than the typical background activity. To effectively visualize and analyze these square waveforms without losing important details, increasing the sensitivity of the EEG recording is warranted.

By adjusting the sensitivity from a lower value, such as 7 µV/mm to a higher value like 10 or 15 µV/mm, the waveform details of the seizure discharges are amplified, making them more discernible on the recording. This adjustment allows for a better interpretation of the seizure activity, as higher sensitivity settings provide a more pronounced representation of the electrical brain activity.

Increasing the sensitivity in this case ensures that the square waveforms remain visible and interpretable, which is essential for accurate diagnosis and treatment planning in patients experiencing seizures.
