چکیده
High resolution multichannel ECG measurement is necessary prerequisite for advanced diagnostics of various cardiovascular diseases. Special multichannel electrocardiograph ProCardio-8 was developed to obtain ECG signals with desired quality. The system is conceived as a virtual instrument with an external intelligent measuring unit connected to a host PC running dedicated application software. In this paper, the data acquisition software developed in MATLAB version 7 and using the Signal Processing Toolbox is introduced. In the first part of the paper, applicability of MATLAB for fast data acquisition was verified and data throughput between the measuring unit and the PC was estimated using a data source with adjustable data rate. Second part of the paper is devoted to development and optimization of a measuring software module that includes control of the measuring unit, testing of electrode contacts and real time data acquisition, visualization and storage of measured data.

The aim of this study was to investigate the application of wavelet denoising in noise reduction of multichannel high resolution ECG signals. In particular, the influence of the selection of wavelet function and the choice of decomposition level on efficiency of denoising process were considered and whole procedures of noise reduction were implemented in MatLab environment. The Fast Wavelet Tra...
متن کاملSoftware design for analysis of multichannel intracardial and body surface electrocardiograms
Analysis of multichannel ECG recordings (body surface maps (BSMs) and intracardial maps) requires special software. We created a software package and a user interface on top of a commercial data analysis package (MATLAB) by a combination of high-level and low-level programming. Our software was created to satisfy the needs of a diverse group of researchers. It can handle a large variety of reco...

Analysis of multichannel ECG recordings (body surface maps and endocardial maps) requires special software. Both interactive usage of a fast and robust user interface and batch job processing for the analysis of large amounts of data is necessary. In addition, the package should be userextensible, because new techniques for the analysis of multichannel ECGs are continuously under development, a...
