Tissue Doppler echocardiography color-coded images and time-velocity curves demonstrating dyssynchrony in a heart failure patient with left bundle branch block
The vertical yellow lines mark the ejection interval and the color-coded curves correspond to the 12 segments. The white arrows indicate the opposing wall delay in time-to-peak velocity from different left ventricular walls.
