Burst EEG pattern is seen in?

Burst suppression is an electroencephalography (EEG) pattern that is characterized by periods of high-voltage electrical activity alternating with periods of no activity in the brain. The pattern is found in patients with inactivated brain states, such as from general anesthesia, coma, or hypothermia EEG video monitoring demonstrates that clinical seizure manifestations may lag behind the sta of ictal EEG activity; bursts lasting less than 3 seconds are usually clinically silent. During the absence seizure, rhythmic eye blinks and mild clonic jerks may be present. As a seizure progresses, automatisms may be seen. Ref Harrison 20th edition pg 1543
