Seizures missed by the SDA. (A) Brief 30 s seizure. 0 of 4 seizures were detected in this record (thr 0.5), though the algorithm output would cause the clinician to interrogate the EEG at various points despite the fact that the fixed threshold was not reached. (B) Subtle, dysrhythmic 2 min seizure with complex morphology, 0 of 1 seizures were detected in this record (thr 0.5). (C) Low amplitude seizure, 31 of 55 seizures were detected in this record (note. Non detected seizures produce clear peaks on the probability trace for interrogation).
