Table 2. Intraclass correlations between simulated BPM and RapidHRV for uncleaned (and cleaned) data as a function of sampling rate and noise.

Sampling rate	0.01 dB	10 dB	20 dB
20 Hz	0.06 (0.18)	0.37 (0.80)	0.98 (1.0)
50 Hz	0.18 (0.13)	0.80 (0.96)	1.0 (1.0)
100 Hz	0.33 (0.26)	0.96 (1.0)	1.0 (1.0)
250 Hz	0.62 (0.7)	1.0 (1.0)	1.0 (1.0)

Note:

Higher values indicate better performance. For readability, data is only reported in a key range of performance (0.01–20 dB noise) where ICC had plateaued at ~0 and ~1.
