In this study we investigate a limited lead system, that reconstructs 12-lead ECGs from leads I, II, V2 and V5, to assess how slight misplacement of recording electrodes impacts on reconstruction accuracy. The study population consisted of 117 lead body surface potential maps (BSPMs) recorded from 559 subjects (approximately one third normal, one third MI and one third LVH). The BSPMs were interpolated...
In this study we have developed a limited lead system to allow reconstruction of the 12-lead ECG. This has been based upon the analysis of eigen-vectors calculated from body surface potential map (BSPM) data. Eigenvectors were calculated from a set of 117 lead BSPMs (normal=172, LVH=178, MI=209). The extrema of the first three eigen-vectors were used to determine the positions of recording sites for...
Past studies have demonstrated the improved diagnostic utility of the electrocardiogram by utilizing alternative recording sites to that used in the standard 12-lead. The present study proposes new lead sets based on the developments of innovative computational models. Utilizing 744 117-lead body surface potential maps the diagnostic value of different recording site combinations was evaluated. Three...
