ECG-ARD: Autoregressive ECG Denoising With Dual-Domain Fusion and a Vector-Quantized Bottleneck.
Electrocardiogram (ECG) recordings are frequently corrupted by nonstationary artifacts such as baseline wander, muscle activity, and electrode motion, which can distort waveform morphology, reduce signal quality, and compromise downstream analysis. Although recent deep learning approaches have improved signal-level fid...
