A 32-year-old woman is evaluated for recurrent paroxysmal events. One of her habitual events is captured during EMU admission with video-EEG monitoring. The displayed EEG epoch corresponds to one of her habitual events. Which of the following corresponds to the EEG finding?

• Generalized 3-Hz spike-and-wave discharges
• Evolving rhythmic theta activity beginning over the right temporal region
• Generalized polyspike-and-wave discharges time-locked to the jerks
• Widespread movement and myogenic artifact without an evolving cerebral ictal pattern
• Lead artifact confined to channels sharing a single loose electrode
• Rhythmic artifact consistently time-locked to the QRS complexes
