Identification of 27 abnormalities from multi-lead ECG signals: an ensembled SE_ResNet framework with Sign Loss function

Abstract: Objective. Cardiovascular disease is a major threat to health and one of the primary causes of death globally. The 12-lead ECG is a cheap and commonly accessible tool to identify cardiac abnormalities. Early and accurate diagnosis will allow early treatment and intervention to prevent severe complications of cardiovascular disease. Our objective is to develop an algorithm that automatically identifies 27 ECG abnormalities from 12-lead ECG databases. Approach. Firstly, a series of pre-processing methods were pr… Show more

“…Therefore, early and accurate diagnosis of ECG plays an important role in preventing severe CVD and can improve treatment outcomes (Artis, Mark, and Moody 1991). Deep learning has been applied to improve the timeliness and accuracy of diagnosis of 12-lead ECG (Hong et al 2020(Hong et al , 2019Zhu et al 2021). However, training deep learning models in a supervised manner often requires a large volume of high-quality labels to achieve strong generalization performance.…”

“…Indeed, the model that generalised best to the test data had the lowest per-class metrics in the validation data (Natarajan et al 2020). We further note that our model architecture was very similar to the entry that placed third in the 2020 Physionet challenge (Zhu et al 2021). The primary difference between the two models, which may explain difference in performance, was our inclusion of age and gender features.…”

“…Recently, researchers have begun to use more sophisticated 1D-CNN architectures, particularly ones whose 2D version achieves high image classification accuracy. Zhang et al [22] proposed using 1D-ResNet34, Zhu et al [23] ensembled two 1D-SEResNet34s and one set of expert rules to identify more types of abnormalities. Furthermore, Yao et al [24] constructed Time-Incremental ResNet18 (TI-ResNet18), a combination of a 1D-ResNet18 and an LSTM network in order to capture both spatial and temporal patterns in ECG signals.…”

“…Detailed performance is presented in Table 2. For precisely benchmarking, we compared LightX3ECG with some popular ECG classification methods, which can be considered state-of-the-art including 1D-ResNet34 [22], 1D-SEResNet34 [23], InceptionTime [40], and TI-ResNet18 [24].…”
