Fig. 3From: Tissue Doppler derived biphasic velocities during the pre and post-ejection phases: patterns, concordance and hemodynamic significance in health and diseaseDot plots for correlations observed in our study in subgroups. Upper panel: correlation between opposite waves of the biphasic PRE velocities (left: between positive PRE and negative POE, right: between negative PRE and positive POE). Middle panel: correlation between the ratio of positive to negative PRE waves (PRE-P/N) vs, the negative to positive POE (POE-N/P). Lower panel: correlations against E/e’ as a representation of LV filling pressures (left: versus the PRE-P/N ratio, right: versus the POE-N/P ratio)Back to article page
