A 10-day-old infant born at 23 weeks 3 days gestation is undergoing continuous EEG monitoring in the NICU. At the time of this recording, the infant is 24 weeks 5 days postmenstrual age (PMA). The patient recently received a midazolam bolus for an electrographic seizure.​ The EEG below demonstrates bursts of high-amplitude activity (>200 μV) separated by prolonged periods of marked background suppression (<5 μV), with no normal background features during the suppressed periods. The interval between bursts is approximately 4 minutes.​ Which of the following best describes this EEG background pattern?​

• Burst suppression
• Trace discontinu
• Trace alternant
• Excessive discontinuity
