    Proposal of Feature Extraction from Wavelet Packets Decomposition of QRS Complex for Normal and Ventricular ECG Beats Classification

  • Original language description

    Long term holter monitoring is widely applied to patients with heart problems such as arrhythmias. The primary task of computer aided systems in holter ECG evaluation is to distinguish between different beat types. In this work we investigate the use ofwavelet packets transform as a mean to extract features capable of providing the information needed by a classifier for discrimination between Ventricular (V) and Normal beats (N). We designed approach for feature extraction based on wavelet packets andtemplate matching. We used MIT database for test of this approach. The database was divided into to subsets (testing and validation) and we obtained sensitivity 97,7% and 91,9%, specificity 95,1% and 87,1%, overall accuracy 96,3% and 90,4% on the first subset and second subset respectively.

    Návrh metody extrakce příznaků z vlnkové transformace QRS komplexu pro normální a ventrikulární srdeční cyklus

  • Czech description

    Práce se zabývá návrhem metody extrakce příznaků z časově frekvenčního prostoru vlnkové trasnformace pro získání popisu ventrikulárního a normální srdečního cyklu. Navržený přístup byl testován na testovací a validační množině zaznamů z MIT databáze a bylo dosaženo výsledků senzitivity 97,7% a 91,9%, secificity 95,1% a 87,1% a celkové přesnosti 96,3% a 90,4%.
