Evaluation of compression quality is essential part of data compression. No unified approach exists in this area and comparison of different algorithms is very difficult. The paper deals with 13 common efficiency and quality ...

Cardiovascular disorders are still the most common cause of death in Western countries. In addition to cardiologists´ care, patient self-examination is the growing area nowadays. For this purpose, mobile devices for ECG ...

Compression of ECG signal is up to date challenge. There are many methods for ECG compression. This paper focuses on fractal based compression method. The method is implemented in MATLAB and compared with results in source ...

This article details my realization of the QRS delineation, based on the method introduced by Laguna, Jané and Caminal, described in the first part. The folowing part describes my realization and modifications aimed at the ...

The aim of this thesis is to present possible technical solution for monitoring sports activity. Electric signals of heart are transmitted into an open-source Arduino platform and results are presented to the user in a ...

Automated analysis of HRV requires reliable detection of QRS complexes. We propose a detection method based on different combinations of three orthogonal (pseudoorthogonal) leads of human ECG signals. ECG signals were ...

The aim of this article is to propose an approach to High-Frequency ECG (HF-ECG) preprocessing with an intention to verify the settled methods of signal preprocessing in the perspective of the new requirements and possibilities ...

Pathology of the ventricular extrasystole is commonly detected by comparing the width and other parameters of the QRS complex. This article represents recognition of extrasystoles using high-frequency ECG components, ...

The aim of this article is to present a pilot case study in the area of body surface potential mapping. This technology was used to record data from animal experiments with the goal to find out, what information could be ...
