Development of Reduced-Lead Body Surface Mapping Systems Using Spatial Frequency Analysis

• Body Surface Maps (BSMs) are starting to be used in clinic. • An enormous amount of data is obtained, which can be cumbersome to handle. Reduction of data can significantly decrease analysis time. • Here, the minimum number of electrodes necessary to reconstruct BSM maps accurately is determined by Lomb-Scargle spatial frequency analysis (LSSA) and singular value decomposition (SVD).
