摘要：
Apparatus, system and method for medical analysis of a seated individual, includes determining the aortic valve opening； the PTT； and calculating the PWV. Determining the aortic valve opening includes collecting BCG data while sitting on a seat and determining the timing of the aortic valve opening, taking into account posture. Measuring the aortic pulse wave transit time includes collecting BCG data while sitting on a seat capable of measuring changes in apparent weight； determining the timing of the aortic valve opening； detecting the arrival of the pulse wave at the end point； and measuring the relative timings of the two events. Calculating the PWV includes determining a length of the arterial segment through which a pulse wave is to be measured between a start point and an end point； and dividing the determined length of the arterial segment by the PTT.
