Muitimodal evozierte Potentiale und Herzratenvariabilität bei komatösen Patienten - Teil 1: Meßmethode und Normbereiche

Abstract: Multimodal evoked potentials and heartrate variability i n comatose patients. Part 1: Method, normative data Multimodal EPs and heartratevariability-masurements in comatose patients have been performed for few years at the university hospitals of Graz and Erlangen.The following date and Parameters are analysed and discussed: brainstem auditory evoked potentials, mechanical evoked longlatency SEP, VEP recorded over the central and occipital region and heartratevariability (HRV). The method of data acquisition a… Show more

“…Furthermore, SNR has been calculated through a variety of methods (Luck, 2005;Spencer, 2005). For example, one method is to calculate the ratio of the largest evoked potential peak-to-peak amplitude and the mean amplitude of the baseline period prior to the presentation of the stimulus (Pfurtscheller et al, 1987). Another method is to divide the standard deviation of the averaged ERP by the standard deviation of the noise as estimated from amplitudes of oscillatory signals recorded during the resting states (Ouyang et al, 2015).…”
