Postanoxic Coma with Myoclonus: Who Might Survive?

EEG patterns predicted recovery for patients with post–cardiac arrest anoxic myoclonus.

Patients with postanoxic multifocal myoclonus (PAMM) and burst suppression on electroencephalography (EEG) are believed to have a very low likelihood of regaining meaningful neurological recovery. However, not all patients with PAMM have a poor prognosis. If so, there wouldn't be patients with Lance–Adams Syndrome — survivors with action myoclonus. Aiming to identify different EEG patterns associated with outcomes after PAMM, researchers studied a cohort of patients ascertained consecutively from the Pittsburgh Post Cardiac Arrest Service during a 3-year period.

Of 401 patients, 69 had PAMM, 65 of whom had complete data available. The vast majority (n=48) had burst suppression with time-locked myoclonus and a similar progression of eventual …
