Use the measurement units shown below. Some fields apply only to a selected method or condition; follow the interactive tool’s method choices. The interactive tool keeps missing measurements incomplete and provides its method-specific results and reference context.
Measurements and acquisition
Mitral E/A ratio
PW Doppler at the mitral leaflet tips
- Place the PW sample between the mitral leaflet tips.
- Record at end-expiration with a clear E and A wave.
- Measure the requested peaks or trace the requested envelope.
Mitral E velocity cm/s
PW Doppler at the mitral leaflet tips
- Place the PW sample between the mitral leaflet tips.
- Record at end-expiration with a clear E and A wave.
- Measure the requested peaks or trace the requested envelope.
Mitral e′
PW tissue Doppler at the mitral annulus
- Reduced
- Not reduced
- Place the sample at the septal or lateral mitral annulus.
- Use tissue-Doppler settings and align with annular motion.
- Measure the early diastolic e′ peak and average representative beats.
LA reservoir strain
Enter the measured value in the displayed unit
- Available
- Unavailable
- Confirm the variable matches the selected formula.
- Use the unit displayed beside the field.
- Keep measurements from the same representative hemodynamic state.
LA reservoir strain %

Lateral E/e′
PW tissue Doppler at the mitral annulus
- Place the sample at the septal or lateral mitral annulus.
- Use tissue-Doppler settings and align with annular motion.
