Calculating optimal virtual lead from multichannel ECG by minimizing morphological beat-to-beat variability


A novel measure of the morphological beat-to-beat variation of signals derived from multichannel ECG is presented. It is used to find an optimal linear functional that maps the electrical activity of the heart into a single virtual lead in the sense of least beat-to-beat variability. The results show that for each subject it is possible to find a virtual… (More)
