A new deep learning model, CaReS-BiNet, effectively classifies electrocardiogram (ECG) arrhythmias by learning local and temporal features. This advanced framework demonstrates high accuracy and robustness across diverse datasets, improving automated arrhythmia detection.

Area of Science:

  • Biomedical Engineering
  • Artificial Intelligence in Medicine
  • Cardiology

Background:

  • Automated electrocardiogram (ECG) arrhythmia classification faces challenges including complex heart rhythms, imbalanced data, and poor generalization across different clinical conditions.
  • Existing methods struggle with the intricate morphological patterns and temporal dependencies inherent in ECG signals.

Purpose of the Study:

  • To develop an advanced deep learning framework, CaReS-BiNet, for robust and accurate automated ECG arrhythmia classification.
  • To address limitations in current models regarding morphological complexity, class imbalance, and cross-dataset generalization.

Main Methods:

  • Proposed CaReS-BiNet: a Convolutional and Residual Squeeze-and-Excitation Bidirectional-LSTM Network.
  • Integrated parallel multi-scale 1D convolutional branches, residual connections, Squeeze-and-Excitation channel attention, and bidirectional LSTM for joint local and temporal feature learning.
