The thesis comes within the area of ECG signal analysis by the HRV analysis. The goal of the thesis is to perform a pilot experiment which should answer a question how serious influence have different types of ECG artifacts on the most important HRV parameters. The thesis comprises four main parts. The first part deals with a theoretical background of the issue, presents a state-of-art of the issue and known HRV methods. HRV parameters of interest (pNN50, SDNN, HF a LF/HF) and different kinds of ECG artifacts (system hum, fluctuation of isoline, abrupt changes of isolines and myopotentials) are introduces in the second part. The main part of the chapter is a design of methods for simulating of selected types of ECG artifacts and a suggestion of methods for result interpreting (box-and-whiskers plots, t-test and Wilcoxon's test). The third part of the thesis describes available and self-designed software (qrsdet.cpp, dviz.exe, hrv.exe resp. zarus.exe, vyhodnot.exe). Selected values of parameters of the disturbings, previews of disturbed ECG signals and the most important results of the thesis including discussion are summarized in the fourth part. Conclusions about influences (sensitivities) of HRV parameters on different kinds and intenzities of ECG artifacts on the basis of performed experiments have been formulated. In general the most sensitive parametr is the SDNN followed by pNN50. Parameters HF and LF/HF are influenced only little and approximately equally, the HF is possibly influenced a little bit more than LF/HF....

Má práce se zabývá snímáním, zpracováním a interpretací dat, naměřenýchpři reálných experimentech na přírodovědecké fakultě Univerzity Karlovy, na katedře parazitologie. Data obsahují jednak elektrofyziologické signály (jako EKG, signál kožního...
This work concerns with the measuring, analysis and interpretation of the data, obtained from real-life experiments carried-out on the Faculty of natural science, Charles University in Prague, department of parasitology. The data sets contain electrophysiological signals (such a ECG, galvanic skin response etc.) and further factors, which are the results of certain psychylogical tests (dedicated for example for the domination vs. submisivity detection). The number of these pair-experiments was 240 ?they contain resting state followed by the psychical stress period. From thepreprocessed data the tachogram was computed and the set of HRV parameters was extracted. Then the HRV parameters were analyzed in correlation with the psychological parameters. Psychological factors of each person were used as filter parameters and theirinfluence to the separation of the rest and stress phasewas observed. Using the results of this analysis the basic principle of the classification algorithm was designed and verified. Mentioned algorithm should be usable as the supplement of the psycholo gical tests....

The first part of the thesis provides an overview of specific methods of compression and encryption which are usable for long-range transport of biological data. The thesis describes a library and newly developed unified application interface for testing of the algorithms. The algorithms are tested on real biological data and their parameters are compared, especially time requirements, compression ratio and ability to work in real time. The whole library is implemented in embedded device based on the ARM9 architecture. Encryption and dec- ryption functionality is verified in real conditions of acquisition and transfer of biological data....
