چکیده

In this paper, a method is described to transform Body Surface Map (BSM) data from one lead system to that of another. This enables pooling of BSM data between different centres. The transformation tool is based upon Laplacian interpolation. It is evaluated by inspecting transformations from lead systems having few leads to one having many leads.

Prediction of dispersed mineralization zone in depth using frequency domain of surface geochemical data

Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...

Filtering of Surface Laplacian Electrocardiograms from Humans to Produce Atrial Activation Patterns

Four digital filtering techniques were evaluated to improve the signal-to-noise ratio (SNR) of directly obtained Laplacian electrograms (LECG), which were bandpass filtered before analog to digital conversion. The moment of activation (MOA) in the LECG was detected to create isochronal body surface maps, which show activation patterns. Unprocessed atrial LECG activity coincided with P-waves in ...

Body Surface Cardiac Propagation Maps of Humans from Laplacian Moments of Activation

In this feasibility study Laplacian electrocardiograms were utilized to generate body surface moment of activation (MOA) maps. The data were obtained with Laplacian sensors from humans. Inverse distance interpolation was applied to improve the image quality. For normal subjects, the MOA maps showed certain common features. A partial activation cycle of atrial flutter was mapped and is presented...
