摘要

这一贡献提出了一种新的扭曲方法，二维信号扭曲(2DSW)，用于跟踪心电图时间间隔的心跳变化。为了评估2DSW在捕捉QT间期细微变化方面的效率，我们将2DSW应用于Physionet QT数据库。研究表明，2DSW可以高度准确地跟踪qrs开始和t端，这使得该方法对未来的临床应用非常有用，特别是对心电图特征的心跳变异性分析。

Measurement of QT variability by two-dimensional warping

This contribution presents a novel warping method, two-dimensional signal warping (2DSW), for tracking beat-to-beat changes in time intervals from electrocardiograms. To evaluate the efficiency of 2DSW to capture subtle changes in the QT interval we apply 2DSW to the Physionet QT database. It is shown that 2DSW allows highly accurate tracking of QRS-onset and T-end, which renders the method useful for future clinical applications, in particular beat-to-beat variability analysis of ECG features.
