Abstract: Provided is a system, method, and device for non-invasive hemodynamic measurement of a subject. The method includes identifying vibrational pulses V1 and V2 and vibrations corresponding to cardiac mechanical motion from vibrational cardiography (VCG) data, the VCG data derived from a vibration signal acquired at the surface of the chest of the subject corresponding to cardiac-induced vibrations; determining a vibration feature from the vibration signal; and determining a hemodynamic measurement from the vibration feature.
