A novel diffusion-based model with a State Space Augmented Transformer can synthesize realistic 12-lead ECGs, potentially addressing privacy concerns in data-driven cardiovascular research.
Cardiovascular diseases (CVDs) are a major global health concern, causing significant morbidity and mortality. AI's integration with healthcare offers promising solutions, with data-driven techniques, including ECG analysis, emerging as powerful tools. However, privacy concerns pose a major barrier to distributing healthcare data for addressing data-driven CVD classification. To address confidentiality issues related to sensitive health data distribution, we propose leveraging artificially synthesized data generation. Our contribution introduces a novel diffusion-based model coupled with a State Space Augmented Transformer. This synthesizes conditional 12-lead electrocardiograms based on the 12 multilabeled heart rhythm classes of the PTB-XL dataset, with each lead depicting the heart's electrical activity from different viewpoints. Recent advances establish diffusion models as groundbreaking generative tools, while the State Space Augmented Transformer captures long-term dependencies in time series data. The quality of generated samples was assessed using metrics like Dynamic Time Warping (DTW) and Maximum Mean Discrepancy (MMD). To evaluate authenticity, we assessed the similarity of performance of a pre-trained classifier on both generated and real ECG samples.
Zama et al. (Mon,) conducted a other in Cardiovascular diseases. Diffusion-based model coupled with a State Space Augmented Transformer vs. Real ECG samples was evaluated on Quality of generated samples (assessed via DTW and MMD) and authenticity (performance of a pre-trained classifier). A novel diffusion-based model coupled with a State Space Augmented Transformer was developed to synthesize conditional 12-lead electrocardiograms to address healthcare data privacy concerns.
