Figure 5From: Prevalence and inter-relationship of different Doppler measures of dyssynchrony in patients with heart failure and prolonged QRS: a report from CARE-HF Tissue synchronization imaging (TSI) showing inferior delayed systolic contraction in red colour with corresponding TVI-curves. The TSI-technique is timesaving and makes it easy to find intra ventricular regions with dyssynchrony. Abbreviations see fig 4.Back to article page
