摘要：

In this paper, a novel multilead (ML) based automatic strategy for delineation of ECG boundaries is proposed and evaluated with respect to the QRS and T-wave boundaries. The ML strategy is designed from a single-lead (SL) wavelet transform based delineation system. It departs from three orthogonal leads and takes advantage of the spatial information provided using a derived lead better fitted for delineation. SL delineation is then applied over this optimal derived lead. The ML strategy produces a reduced error dispersion compared to SL results, thus providing more robust, accurate, and stable boundary locations than any electrocardiographic lead by itself and outperforming strategies based on lead selection rules after SL delineation.
