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.
本文提出了一种基于多导联（ML）的新型心电图边界自动划定策略，并针对QRS波和T波边界进行了评估。该ML策略是从基于单导联（SL）小波变换的划定系统设计而来。它从三个正交导联出发，利用通过更适合划定的派生导联提供的空间信息。然后在这个最优派生导联上应用SL划定。与SL结果相比，ML策略产生的误差离散度降低，因此比任何单个心电图导联本身都能提供更稳健、准确和稳定的边界定位，并且优于基于SL划定后导联选择规则的策略。
