Abstract

ORIG CZ

V originále

The flexible electro-optical recording system, which allows simultaneous recording of electrograms from orthogonal leads and action potentials from an arbitrary site on heart surface, is presented. The recorded action potentials are disturbed with noise from multiple sources. A robust QRS-complex detector with the following modified averaging with filtered residue is proposed. Adding the filtered residue back to the averaged signal helps to keep information on trends in the signal.

In Czech

V práci je popisován flexibilní elektro-optický systém, který umožňuje současné snímání elektrogramů z ortogonálních svodů a akčních potenciálů z povrchu srdce. Záznam akčních napětí je rušen několika způsoby. Aby bylo rušení minimalizováno, je navrhován robustní detektor QRS komplex s následným průměrováním a filtrováním reziduálního signálu. Toto reziduum je pak přidáno k průměrnému signálu a tak je uchována informace o trendech v signálu.
