Percentage EGG Classification

• Calculates the percentage of Bradygastria,
  Normal, Tachygastria and Arrhythmia based on
  results from the Running Spectrum Analysis.

14
Percentage Distribution of EGG Power

• Calculates the percentage distribution of the
  EGG-power for the Bradygastria, Normal,
  Tachygastria and Duo ares.

15
Dominant Power and Frequency

• Based on results from the Overall Spectrum
  Analysis and the Percentage of EGG Classification.

16
Power Instability Coefficient

• Based on a standard deviation calculation and the
  Dominant Power and Frequency calculation.
