Table 1 Overall performance summary of each algorithm at SNRs of 10, 20, and 40 individually and the fusion results using the purity signal quality indices. All figures are RMS error in BPM. Note that both EDR_RS and the QRS-Area (EDR_G) methods perform poorly at low breathing rates, while EDR_RSA performance degrades at higher respiratory rates.
