1. Normal MV inflow Doppler:
2. Isovolumic Relaxation Time
(Duration between closure of AoV and Opening of MV)
Measured from CW Doppler trace that has both LVOT and MV flows.
3. Deceleration time
Deceleration time for E wave.
(Measured from PW Doppler of Mitral inflow) 
4. Comparison of Ar duration (in PV Doppler) with A wave duration (in MV inflow Doppler): 
4. Comparison of Ar duration (in PV Doppler) with A wave duration (in MV inflow Doppler):
