ABRET EEG Exam Review Questions With All Correct Answers (100 Verified)-21

Decreased time base (analysis time/display time/epoch) or increase paper speed, to spread out the waveforms to better resolve the fast activity and spikes. How did this change improve the sample above in question 134 ? (In the sample below, the same data is modified and reformatted again. What parameter changed in the following sample? How does this help?) a. Better localization of focus b. Better resolution of spike morphology and anterior dominance c. Enhanced analysis of EKG monitor d. Better display of lateralization - Better resolution of spike morphology and anterior dominance The sample below is from a 32 year old patient with confused state, left arm and left facial twitching. What is seen in the sample that is consistent with the patient's history? a. PVCs b. Excessive EMG activity c. Normal background rhythms d. Right temporal-central epileptiform activity - Right temporal-central epileptiform activity In the sample above, what abnormality unrelated to the patient's history is seen? a. Premature ventricular contractions b. Burst suppression c. REM onset sleep d. Hypoglycemia - Premature ventricular contractions In the sample below, the 22 week old patient is stated to be in Stage Il sleep. What is the evidence that the patient is in Stage Il sleep? a. Vertex Sharp Waves b. Spindles c. Decreased EMG d. Absence of alpha - Spindles Cancellation occurs when a. the two electrodes in a channel are both inactive b. Input 1 is higher in voltage than Input 2 c. The voltage in Input 1 is the same as the voltage in Input 2 d. The reference electrode is truly inactive -
