Abstract
A method for measuring cardiac pressure includes positioning a fluid-filled catheter and a pressure wire sensor at a cardiac pressure calibration location. A first pressure measurement is acquired from the fluid-filled catheter and a second pressure measurement is acquired from the pressure wire sensor. A set of equalization parameters is identified to apply to the first pressure measurement to reduce an error between the first pressure measurement and the second pressure measurement. The equalization parameters include a frequency correction parameter and a damping correction parameter to correct for frequency and damping of oscillations in the first pressure measurement. A third pressure measurement is acquired from the fluid-filled catheter. The set of equalization parameters is applied to equalize the third pressure measurement.
