RV ESTVI-LV contractility relationship during changes in different loading conditions.
<p>Correlations between changes in RV end systolic TVI (ESTVI) and in left ventricular (LV) stroke volume (SV) or maximum of the first derivative of LV pressure (dP/dt<sub>max</sub>) during preload reduction (A,B) and increase of LV afterload (C, D). Changes normalized to baseline values.</p
ESTVI (A), EDTVI (B) and pk-pk TVI (C) changes during different loading and inotropic conditions. * <i>p</i><0.05 vs baseline; # <i>p</i><0.05 vs LDDS.
