Composite of representative EEG tracings. (A) Background EEG abnormalities on the fifth day of life. EEG trace demonstrates a burst-suppression pattern, at times with polyspikes and sharp waves for bursts of five seconds and interburst intervals of one to three seconds (speed: 1.0 mm/s). (B) Ictal EEG displaying seizure onset with fast low-amplitude spikes arising from right centro-temporal areas on Day 26. Lidocaine infusion was started on the same day, following increased seizure burden over the preceding 24 hours (speed: 10 mm/s). (C) Postictal EEG demonstrating 4 to 5-Hz rhythmic theta waves of lambdoid morphology over the right posterior quadrant immediately after cessation of electrographic seizure activity on the sixth day of life (speed: 30 mm/s).
