As a major cause of death worldwide, cardiovascular diseases-especially arrhythmias-require the creation of precise and automated technologies for early diagnosis and detection. To identify arrhythmias from electrocardiogram (ECG) signals, this paper introduces a deep learning-based classification model that focuses on five main heartbeat types: Normal (N), Left Bundle Branch Block (L), Right Bundle Branch Block (R), Atrial Premature Beat (A), and Premature Ventricular Contraction (V). We leverage Lead I signals from several sources, such as the INCART 12-lead, Sudden Cardiac Death Holter, Supraventricular, and MIT-BIH Arrhythmia databases, yielding more than 3.9 million training and 112,575 testing segments. Examples of data preparation include 180 sample, fixed-window segmentation, Min-Max normalization, and class balancing with the Synthetic Minority Over-sampling Technique (SMOTE). The hybrid architecture uses Transformer layers to model temporal dependencies and 1D Convolutional Neural Networks (CNNs) to extract spatial features. The Adam optimizer with dropout and batch normalization for regularization trains the model. The proposed system outperforms the TN4 model and other cutting-edge benchmarks, achieving 99.99% accuracy, precision, and F1-score across all classes. Feature robustness is further improved by applying deep hybrid architectures and convolutional neural networks, which were motivated by earlier studies. The suggested paradigm advances artificial intelligence-driven, individualized digital healthcare and has great promise for scalable, real-time arrhythmia identification.
作为全球主要死因,心血管疾病——尤其是心律失常——需要创建精确且自动化的早期诊断和检测技术。为了从心电图(ECG)信号中识别心律失常,本文介绍了一种基于深度学习的分类模型,该模型专注于五种主要心跳类型:正常(N)、左束支传导阻滞(L)、右束支传导阻滞(R)、房性早搏(A)和室性早搏(V)。我们利用来自多个来源的I导联信号,如INCART 12导联、心脏性猝死动态心电图、室上性和麻省理工学院-贝斯以色列女执事医疗中心心律失常数据库,得到了超过390万个训练片段和112575个测试片段。数据准备的示例包括180个样本、固定窗口分割、最小-最大归一化以及使用合成少数过采样技术(SMOTE)进行类别平衡。混合架构使用Transformer层对时间依赖性进行建模,并使用一维卷积神经网络(CNN)提取空间特征。带有随机失活和批量归一化进行正则化的Adam优化器对模型进行训练。所提出的系统优于TN4模型和其他前沿基准,在所有类别上均实现了99.99%的准确率、精确率和F1分数。通过应用受早期研究启发的深度混合架构和卷积神经网络,进一步提高了特征鲁棒性。所建议的范式推动了人工智能驱动的个性化数字医疗保健发展,对于可扩展的实时心律失常识别具有巨大潜力。
