  • Summary

    When evaluating a patient on continuous EEG monitoring at the bedside, the two fundamental questions a reader must ask themselves are: a) is the patient encephalopathic? and b) if so, is this due to epileptiform activity or seizures? This chapter describes a simple method of rapid bedside EEG interpretation using three easy steps. The first step is to analyze the background for continuity, symmetry, voltage, and the presence of a posterior dominant rhythm. The second step involves searching for abnormal waveforms, such as slow or sharp waves, and the third step involves recognizing artifacts. Sharp waves are associated with seizure activity. Finally, the chapter also describes the significance and method for testing reactivity and grading the severity of encephalopathy.
