A specific problem using the public access defibrillators arises at the railway stations.
Some countries as Germany, Austria, Switzerland, Norway, Sweden and Slovenia are
using AC railroad net power-supply system with rated frequency of 16.6(6) Hz,
frequency modulated from 15.69 Hz to 17.36 Hz. The power supply frequency
contaminates the electrocardiogram (ECG). It is difficult to be suppressed or eliminated
due to the fact that it considerably overlaps the frequency spectra of the ECG. The
interference impedes the automated decision of the public access defibrillators
whether a patient should be (or should not be) shocked.
The aim of study of this thesis is the suppression of the 16.6(6) Hz interference
generated by the power supply of the railway systems in few central european
countries. For this purpose, an adaptive filter and a band-stop filter are used and the
results obtained are compared in order to get the most suitable solution. [--]
