LV/RV Contractility (dp/dt)


Dp/dt represents the ratio of pressure change in the ventricular cavity during the isovolemic contraction period.

LV dP/dt is estimated by using time interval between 1 and 3 m/sec on MR velocity spectrum.

(Normal LV dp/dt is > 1200 mmHg/s).

RV dP/dt is estimated by using time interval between 1 and 2 m/sec on TR velocity spectrum.
