Abstract
This invention relates to a method and system for monitoring, determining by measurement and calculation and graphically displaying physiological variables related to blood pressure. At least two physiological variables, arterial pressure (Pa) and distal coronary pressure (P ), are detected by and derived from a guidewire-mounted pressure sensor. The Myocordial Fractional Flow Reserve (FFR ) is determined by calculating a ratio P /P from the measured physiological variables (P , P ) and a graph is formed and displayed of the data resulting from the calculation. The invention also provides an interactive graphical user interface system for controlling the calculation of and for displaying, in at least one screen on a display in a monitoring unit, intermediate and final results of the method.
