For the dp/dt of the LV, we use the CW-Doppler of the MR jet. Here it takes 10.56 msec to get from 1 m/s to 3 m/s. Here the dp/dt is 3030 mmHg/sec, well above the 1200 mmHg/sec threshold for LV systolic dysfunction

In comparaison, for the RV - we take the CW-Doppler of the TR jet. Here it takes 15.84 msec to go from 1 m/s to 2 m/s for the RV by the CW-Doppler of the TRJ. It represents 758mmHg/s, which is above ≥ 400 mmHg/s, likely normal.
