摘要：
A method for assessment and/or monitoring a person's cardiovascular state comprises: using a sound and vibration transducer to acquire a vascular sound signal in order to detect a vascular sound from a cervical, thoracic, abdominal, pelvic, or lower limb region of the person； filtering the vascular sound signal to isolate the vascular sound, said filtering using a filter which attenuates frequencies below a lower cut-off frequency in a range of 100-300 Hz； and analyzing the filtered sound signal in order to determine whether an indication of a dicrotic notch in the vascular sound exceeds a set threshold.
