Farzad et al [4] focused the detection the specific fiducial points of the Seismocardiogram (SCG) signal with or without using the Electrocardiogram (ECG) R-wave as the reference point.

Heart rate variability analysis using a
seismocardiogram signal.
Three cardio signals were analyzed: electrocardiogram (ECG), which reflects the electric heart activity; impedance cardiogram (ICG)--reveals the haemodynamic properties of the cardiovascular system; seismocardiogram (SCG) that shows the changes of heart mechanic activity.
