WebJul 21, 2010 · EEG patterns other than slowing associated with acute encephalopathy. Triphasic waves. Triphasic waves were first described in 1950 as blunted spike and wave (19). They were later described as a main deflection downward preceded and followed by a lower amplitude upward deflection giving rise to a triphasic contour (04). WebConclusions: Triphasic morphology GPDs confer less risk of seizures when compared with patients with GPDs without triphasic morphology. Features with a higher risk of seizures include focality on electroencephalogram, interburst suppression, a history of epilepsy, and an abnormal scan. olive bank community club
