Zusammenfassung:The invention provides a seismocardiograph system, which includes an accelerometer, adapted to obtain accelerometer data from user, and a bandpass filter, adapted to filter the accelerometer data. The system further includes an envelope filter, adapted to suppress S2 peaks in the band pass filtered accelerometer data, wherein the envelope filter comprises: a low-pass filter; and a comb filter, wherein the delay of the comb filter is tuned to a left ventricle ejection time (LVET).
