- Primary Outcome Measures
Name Time Method To evaluate the correlations between myocardial velocity index (e'), flow propagation velocity (Vp), strain rate index (ESR) and time constant (tau) or LV filling pressure.
- Secondary Outcome Measures
Name Time Method To compare the accuracy for estimating LV relaxation and filling pressure between the measuring methods of e', Vp, and ESR.
