Zusammenfassung
Introduction: Regularity is assumed to be the definitive criterion to distinguish fibrillation potentials and positive sharp waves from other forms of electrical activity in resting muscle. In clinical routine regularity is established acoustically. We wanted to determine the threshold for examiners to detect irregularity in spike trains. Methods: Audiofiles with spike trains were generated as follows: A positive sharp was repeated at a regular rate of 1Hz 20 times. Each PSW was shifted according to a Gaussian random variable. The irregularity of the files was quantified as 2000*mean(|ISI(i+1)-ISI(i)|/(ISI(i+1)-…
