Originální abstrakt

Microvolt-level electrical T wave alternans (TWA), defined as a consistent 2:l variation in the T wave morphology has been recognized as a marker of electrical instability in a wide range of experimental and clinical situations, such as congenital long QT syndrome, myocardial ischemia and infarction and several other pathologic conditions. On the other hand [1], TWA is an arrhythmia risk marker to assess subtle changes in repolarization that has been introduced for arrhythmia and Sudden Cardiac Death (SCD) risk stratification.Two classes of signal processing techniques which have been applied to a variety of problems are Homomorphic filtering (Cepstral analysis) and Spectral analysis (based on Fast Fourier Transform (FFT)). In this article a simulation study of T wave alternans (TWA) detectors is tested in order to compare the performance of FFT analysis and Cepstral analysis in sliding window mode.
