From: Unified frame of reference improves inter-subject variability of seismocardiograms
Rotation of seismocardiograms. The leftmost column shows the original unrotated signal of a subject, the plots in the middle show the original signal rotated so that the line connecting the two most distant points is parallel to the z axis (frame 1), and the rightmost column shows the original signal rotated so that the line connecting the MC and AO points is parallel to the z axis (frame 2). The units are in mg.
