Effect of Biventricular Pacemaker Optimization on VTI and MPI Measured by Echo Doppler. Effect of biventricular pacemaker optimization on LV VTI and MPI measured by echo Doppler. Baseline and optimal LV VTI (left panel) and baseline and optimal MPI (right panel) measured by echo are shown in each study subject. VTI, velocity time integral; MPI, myocardial performance index. MPI was feasible in 33 patients due to atrial fibrillation in 4 patients.
