摘要:

基于深度学习的ECG分析领域主要由卷积架构主导。这项工作探讨了应用最近推出的结构化状态空间模型(SSM)作为一个特别有前途的方法,由于其能够捕捉长期的依赖关系的时间序列的前景。我们证明,这种方法导致显着的改善,目前的最先进的心电图分类,我们追溯到个人的病理。此外,该模型的能力,以捕捉长期的依赖关系,可以阐明长期存在的问题,在文献中,如最佳采样率或窗口大小,以训练分类模型。有趣的是,我们没有发现使用500 Hz采样数据的证据,而不是100 Hz,并且将模型的输入大小扩展到3s以上也没有优势。基于这个非常有前途的第一次评估,SSM可以发展成为一个新的建模模式的心电图分析。

英文摘要:

The field of deep-learning-based ECG analysis has been largely dominated by convolutional architectures. This work explores the prospects of applying the recently introduced structured state space models (SSMs) as a particularly promising approach due to its ability to capture long-term dependencies in time series. We demonstrate that this approach leads to significant improvements over the current state-of-the-art for ECG classification, which we trace back to individual pathologies. Furthermore, the model's ability to capture long-term dependencies allows to shed light on long-standing questions in the literature such as the optimal sampling rate or window size to train classification models. Interestingly, we find no evidence for using data sampled at 500Hz as opposed to 100Hz and no advantages from extending the model's input size beyond 3s. Based on this very promising first assessment, SSMs could develop into a new modeling paradigm for ECG analysis.
