Method and apparatus for determining cardiac motion feature

Abstract

An apparatus to determine a cardiac motion feature and a method thereof. The method includes: acquiring wireless signals reflected by multiple body parts via a wireless sensing device; filtering the acquired wireless signals using a single-band filter or a multi-band filter, to obtain filtered time domain signals; calculating signal quality evaluation values for evaluating signal quality of the filtered time domain signals; selecting candidate signals from the filtered time domain signals according to the signal quality evaluation values; and determining a cardiac motion feature based on the candidate signals. The method is easy to implement and easy to operate, which can not only guarantee accuracy of the obtained cardiac motion feature, but also has a strong anti-noise capability and high privacy protectiveness.
