pg. 2 Cortical EEG recording can be obscured in patients who are tense or anxious due to?myogenic artifact An EEG record has three per second spike/wave discharges. Both the spike and the slow wave have voltages of 100 µV. If this discharge is recorded with a low frequency filter of 5 Hz and a sensitivity of 10 µV/mm, what would be the deflection of the spike and the wave?
- spike 10 mm, wave 6 mm
- spike 6 mm, wave 10 mm
- spike 10mm, wave 10 mm
- spike 6 mm, wave 6 mm - ANSWER-spike 10 mm, wave 6 mm
