چکیده
1 Executive Summary This paper presents a study of the possibility to collect heart electric potentials from a rectangular region of the precordial area, using a bioelectrical signal amplifier (BESA) with only 4 input channels and to assemble these signals in order to obtain a more complex result such as Body Surface Potential Mapping (BSPM). The introductory part contains the rationale of the paper, focusing on the BSPM both from medical diagnosing and technical issues points of view. Further, the technical aspects of the bioelectric signal amplifier (BESA) and of the analog-digital converter (ADC) are discussed and an experiment is described followed by results and conclusions.

Pseudo Body Surface Potential Mapping on Heart using 3D Wavelet Transform
Body surface potential mapping (BSPM) is used to detect real diagnostic information about the myocardium state more than the standard 12-lead electrocardiogram (ECG). The present research introduces a practical solution for recording body surface potential maps using the standard 12-lead ECG with different positions. It is called pseudo BSPM where all channels were not read out simultaneously. ...

Using 49 capacitive-coupled electrodes, mattress-type harness was developed to obtain posterior body surface potential map (P-BSPM) in dressed individuals. The aim of this study was to investigate how valuable information P-BSPM could provide, especially in discrimination of old myocardial infarction (OMI). P-BSPM of 59 individuals were analyzed; 23 normal control, 11 right bundle branch block ...
متن کاملBoundary Element Method in Spatial Characterization of the Electrocardiogram
The electrochemical activity of the heart gives rise to an electric field. In electrocardiography, cardiac electrical activity is assessed by analyzing the potential distribution of this field on the body surface. The potential distribution, or the set of measured surface-voltage signals, is called the electrocardiogram (ECG). Spatial properties of the ECG can be captured with body surface pote...
متن کاملAnalysis of the electrical heart field.
There are three basic procedures used for an assessment of the electrical heart field from the body surface: standard electrocardiography, vectorcardiography, and body surface potential mapping (BSPM). BSPM has two major advantages over both other methods: 1) it allows exploring the entire chest surface, thus providing all the information on the cardiac electric field available at the body surf...
