Figure 3

Histograms show frequency of differences in RAP between identical Signals 1 and 2 in patients 1 and 20. Histograms of differences in RAP between identical 4-min periods of Signal 1 and 2 are shown for PatID’s 1 [a; mean difference (+std) = 0.02±0.36, n = 685], and 20 [a; mean difference (+std) = −0.17±0.45; n = 718]. The histograms illustrate that despite minor mean difference in RAP between Signals 1 and 2 of all 4-min periods, the frequency of major negative and positive differences in RAP can be extensive.
