A novel low-complexity R-peak detection algorithm with adaptive thresholding achieves high sensitivity and positive predictive value for wearable ECG devices during dynamic activities.
Rodrigues et al. (2021) studied ECG R-peak detection (n=4). Low-complexity R-peak detection algorithm with adaptive thresholding vs. Common QRS detectors was evaluated on R-peak detection Sensitivity (Se) and Positive Predictive Value (PPV). A novel low-complexity R-peak detection algorithm achieved a sensitivity of 99.77% and a positive predictive value of 99.18% during dynamic conditions.
