A Novel Adaptive Spectrum Noise Cancellation Approach for Enhancing Heartbeat Rate Monitoring in a Wearable Device [PDF]

IEEE Access, 2018
This paper presents a novel approach, adaptive spectrum noise cancellation (ASNC), for motion artifacts removal in photoplethysmography (PPG) signals measured by an optical biosensor to obtain clean PPG waveforms for heartbeat rate calculation.

Heartbeat perception is causally linked to frontal delta oscillations [PDF]

Communications Biology
The ability to accurately perceive one’s own bodily signals, such as the heartbeat, plays a vital role in physical and mental health. However, the neurophysiological mechanisms underlying this ability, termed interoception, are not fully understood ...

AF-DETR: Transformer-Based Object Detection for Precise Atrial Fibrillation Beat Localization in ECG [PDF]

Bioengineering
Atrial fibrillation (AF) detection in electrocardiograms (ECG) remains challenging, particularly at the heartbeat level. Traditional deep learning methods typically classify ECG segments as a whole, limiting their ability to detect AF at the granularity ...
