Abstract

V originále

Changes of systolic blood pressure cause changes of inter-beat intervals beat-to-beat by baroreflex. The sensitivity of this heart response is usually quantified as baroreflex sensitivity in ms/mmHg. Two techniques based on wavelet transform are proposed. The first one is based on continuous wavelet transform (CWT) and is similar to the alpha technique. The second is based on the fast wavelet transform (FWT) and uses approximation and detail coefficients of signal FWT as filtered signals. This method has some similarities with so-called modified complex demodulation technique.

In Czech

Změny systolického krevního tlaku vyvolávají změny trvání tepových intervalů baroreflexem. Citlivost odpovědi srdce je kvantifikována jako citlivosti baroreflexu Byly navrženy dvě metody zaoložené na vlnkové analýze. První založená na kontinuální vlnkové transformaci (CWT) je podobná alfa indexu. Druhá je založená na rychlé vlnkové transformaci. Tato metoda je podobná modifikované komplexní demodulací.
