Figure 2 Correlation between the changes in the parameters of ventricular dyssynchrony and those of cardiac output (CO). A high correlation is shown between the changes in the index of dyssynchrony, the intraventricular delaypeak, and the changes in CO; lower correlation for the extent of myocardium displaying delayed longitudinal contraction (DLC); no correlation for the interventricular delay (intra-LV delay). LV = left ventricular.
