Influence of the offset (β) on the generation of blocks of interest on overall accuracy. (A,B) QRS detection; (C,D) systolic wave detection; (E,F) a wave detection; and (G,H) heart sound detection. The impact of the β value on the coupling by scoring >50% accuracy is represented in the left column, while the non-coupling is represented in the right column. The coupling is referred to with accuracy >50%, while non-coupling is referred to with not-a-number (NaN).
