QUANTITATIVE SEISMOCARDIOGRAPHY

A quantifying of the function of a beating heart is disclosed, in which a signal is recorded with an accelerometer placed on the chest of a person. A plurality of segments of the signal are formed, which are aligned and filtered with a band-pass filter having a lower cutoff frequency below 1 Hz and an upper cut-off frequency in the range 100-250 Hz. A mean segment is then determined, in which a first temporal feature is determined. A measure is then determined based on at least one of the signal value, or amplitude, of the first temporal feature and the location in time of the first temporal feature. The determined measure is then provided as output information. 公开了跳动的心脏的功能的量化，其中用放置在人的胸部上的加速度计记录信号。形成信号的多个段，这些段被对准并用具有低于1Hz的下限截止频率和在范围100-250Hz内的上限截止频率的带通滤波器进行滤波。然后确定平均段，其中确定第时间特征。然后，基于第时间特征的信号值或振幅中的至少个和第时间特征的时间位置来确定度量。然后所确定的度量作为输出信息被提供。
