SYSTEM FOR DETERMINING CORONARY PULSE WAVE VELOCITY

摘要

The invention concerns a system for determining coronary pulse wave velocity, comprising: - an interface for receiving proximal and distal blood pressure signals; - a processing device for: - identifying the start time Tfmp of a rising edge and the start time Tfdp of a falling edge of a received proximal pressure signal; - calculating the time period T between times Tfdp and Tfmp; - identifying the start time Tfdd of the falling edge from a distal pressure signal; - identifying the start time Tfmd of the rising edge of the distal pressure signal, after having subtracted said time period T from the time Tfdd; - retrieving the value of the distance between the proximal and distal pressure measurement locations; - calculating the time period separating the start of the identified rising edges; - calculating the coronary pulse wave velocity depending in said time period.
