PLM, Sleep Spindle, and K-complex According to accepted sleep scoring standards, if other scoring criteria are met THESE activities would be considered an event when each is 0.5seconds in duration. Sinus Arrhythmia EKG tracing tracing shows an irregular rhythm without alterations to the QRS and T waves would be what type of arrhythmia? Mechanical Baseline Vertical position of the pens with the polysomnograph amplifiers turned off is referred to as Nocturnal myoclonus The...

psg Practice Exam #2 questions and answers 100% correct What is an appropriate filter setting? EEG 0.3/35, EOG 0.1/35, EKG 1.0/35, EMG 10/70 What is the purpose of the LFF? Eliminating unwanted slow frequencies. DC amplifiers do not have LFF. The ROC electrode is placed out and up from the outer corner of the right eye, and the LOC electrode is placed out and down from the corner of the left eye. If the ROC channel on the PSG is channel 5, and the LOC is channel 6, what will the...
