Abstract: A system for assessing a vascular condition includes a pressure sensing catheter and a pressure guidewire. Heartbeats of the patient can be detected while the pressure sensing catheter and the pressure guidewire are positioned at the proximal position and at a distal position respectively. A diastolic pressure ratio zone (dPR zone) is located within a heartbeat from analysis of a signal from at least one of the pressure sensing catheter and the pressure guidewire. The dPR value can be obtained by calculating an average of several ratios of Pa to Pd taken over time within the heartbeat. A multi-beat metric (dPRc) is calculated that includes the dPR value and that also includes a high frequency sample whole heartbeat pressure ratio.
