Advanced intracardial biosignal processing

In this work deals about the efficient intracardial ECG analysis algorithm. The main focus was design an optimal detection method for intracardial signals based on essential intracardial measuring methods and basic principles of gathering and processing data from invasive catheters. Intracardial ECG analysis is further important step in heart behavior understanding, especially its electric manners. Detailed signal description generated in heart,together with heart function knowledge can provide us with an useful information about hearts condition or its diseases. Designed detection methodis able to mark significant points in intracardial records, compute its elemental parameters and important time intervals. Incurred algorithm was designed and tested on intracardial records provided by Cardiology Clinic of Hospital IKEM --- Praha, and Electrophysiology Laboratory of Hospital Podlesi --- Trinec.

ECG Width Intervals Detection Using Mathematical Methods

Abstract This paper is engaged in region of valid ECG signal processing, so the algorithm development of the QRS complexs assignation from twelve lead surface ECG record, design of measuring system in MATLAB software and file processing of clinical dates. The algorithm makes use of standard mathematical methods and new method used for signal processing – wavelet transform. Created system is assessed on dates of patient, which are treated by biventricular pacing. Dates are provided by cardiological clinic of hospital IKEM in Prague.
