System for measuring the pulse wave velocity of coronary arteries

摘要

The present invention is a system for measuring the pulse wave velocity of coronary arteries; comprising an interface for receiving proximal and distal blood pressure signals; and a processing unit, said processing unit comprising: Identify the start time Tfmp of the rise of the proximal blood pressure signal received and the start time Tfdp of the fall;-calculate the duration T between the time Tfdp and Tfmp;-the start time of the fall of the distal blood pressure signal Identifying Tfdd;-subtracting the time period T from the time Tfdd, then identifying the onset time Tfmd of the rise of the distal blood pressure signal;-the value of the distance between the proximal and distal blood pressure measurement locations Calculating the time period separating the onset of the identified rise; calculating the pulse wave velocity of the coronary artery based on said time period.
